Talk:Friday the 13th/Archive 3

Edit request on 14 September 2013
Friday is also the day when Jesus Christ was crucified, according to the Gospels,[citation needed] making it through folklore and adding to its unpopularity. [citation needed] should be replaced with this: and Chapter 13 in the Gospel of John is where the last supper is written in scripture as the event at which Jesus predicts Judas' betrayal, Autisticrev (talk) 04:42, 14 September 2013 (UTC)Jonathan D.

Notable people who died on Friday the 13th
For substantially the same reasons as set out in, above, I'm cutting the section "Notable people who died on Friday the 13th". As noted above, any given death has a 0.005% chance of occurring on Friday the 13th, and given the massive number of biographical articles of dead people on Wikipedia, you'd have a list potentially thousands of names long.

Auto-archiving?
52 (53, now) subjects on this page, going back 7 years. The page was last culled, manually, in 2007. Any objection to me turning on auto-archiving? TJRC (talk) 22:05, 25 February 2014 (UTC)


 * No objections in over a week, so I'm turning on archiving. TJRC (talk) 20:53, 5 March 2014 (UTC)

Notable people born on Friday 13th
I have removed this section from the main page, because although four of these seven have WP pages which give their birth dates, I can't figure out who the other three people are. I have however wikified the list, so here it is for posterity.

Nick Levine (talk) 10:41, 29 January 2014 (UTC)


 * I strongly agree Nick, having had a a quick scan through other date pages I estimate that there are at least 200 people who could be included in the list. What is the point! The whole concept of Friday 13th requires little more space than Rabbit rabbit rabbit or Spilling salt. This article has attracted an accretion of almost irrelevant nonsense and stuff based on false logic. The more flotsam and jetsam that washes up on the shores of the article the more important it seems. Richard Avery (talk) 12:27, 29 January 2014 (UTC)


 * And now we have another list, this time of people who died on Fri.13. It seems to be a very short list! So I guess not many "well known" people have died on F13. So not such an unlucky day. I will remove this pointless table shortly unless anyone can make a reasoned and convincing case to keep it. Richard Avery (talk) 12:51, 14 February 2014 (UTC)


 * My back-of-envelope calculation is that any random birthday, or any date, really, has about a 0.005 (i.e. $$\textstyle\frac{1}{2}$$%) chance of falling on a Friday the 13th. While that number looks small at first glance, a quick gander at Category:Living people tells us that Wikipedia currently has 650,127 BLP articles; so a list of those born on Friday the 13th would be more than 3000 names long.  (Nitpick; sure, maybe we don't have birth dates for, say, half those people, so, okay, maybe only 1500 names long.  But counterbalancing that, the 650,127 figure counts only living people.  There are probably at least as many notable dead people as living people, so it's probably a wash.)


 * The list is presumably comparably long in determining those who died on a Friday the 13th.


 * Obviously adding two lists of 3000 names each here is not an improvement to the article. If someone really thinks that indicating whether someone was born (or died) on a Friday the 13th is really worthwhile, look into creating a category, i.e. category:People born on a Friday the Thirteenth and/or category:People who died on a Friday the Thirteenth, and tag the articles where you think that's worthwhile.  But please, let's not clutter this article. TJRC (talk) 23:15, 14 February 2014 (UTC)


 * Well said. At the same time and for the same general reason there should be a list of "People Who Died Within 3 months of Walking under a Ladder" or "People who Died after their Path was Crossed by a Black Cat". What is the point? Richard Avery (talk) 13:06, 26 February 2014 (UTC)


 * Uh-oh, now you've done it. See Black cat (superstition)#Notable deaths. TJRC (talk) 18:30, 26 February 2014 (UTC)

Contradiction!
In the history section, the following two sentences appear:
 * "According to folklorists, there is no written evidence for a "Friday the 13th" superstition before the 19th century."
 * "Friday has been considered an unlucky day at least since the 14th century's The Canterbury Tales, and many other professions have regarded Friday as an unlucky day to undertake journeys or begin new projects."

These appear to be contradictions to me.

~ QuasiAbstract {talk/contrib} 13:25, 11 June 2014 (UTC)
 * Fridays have long been thought to be unlucky. The number 13 has long been thought to be unlucky.  However, it was not until the 19th century that people started thinking that a Friday the 13th is unluckier than other Fridays, and the superstition didn't really catch on until the 20th century.  We need to clarify the article.  John M Baker (talk) 14:59, 11 June 2014 (UTC)

Crucifixion of Christ
It appears that everyone believes that Jesus was crucified on Friday. This is not true. Although we celebrate his death on Friday the truth is that he was crucified on Wednesday the day before the preparation which is Hebrew Thursday. It starts at 6pm Wednesday night. Just read the book of Leviticus of the Old Testament. It hard to believe we live in a period that the truth should be known and it isn't. Even Wikipedia can't get it right! — Preceding unsigned comment added by 71.72.0.84 (talk) 20:43, 13 February 2015 (UTC)

3 Friday the 13ths
A year with 3 Friday the 13ths can either be a leap year starting on Sunday (dominical letter AG), with the Friday the 13ths in January, April, and July; or a common year starting on Thursday (dominical letter D), with the Friday the 13ths in February, March, and November.

Why the mention of a particular airplane crash?
The section on the plane crash is hardly relevant to an entry about a superstition. It sounds like an attempt by a pious vandal to lend credence to the irrational fear of Friday the 13th. For balance and perspective, it would be reasonable to include references to all the plane crashes that did *not* occur on a Friday the 13th. But this is supposed to be an *encyclopedia* entry on a particular superstitious belief rather than a polemic or mystical pamphlet. The section on the famous plane crash does not belong here and should be removed, since it is as irrelevant to this entry as any other well-known event that happened to have occured on Friday the 13th. — Preceding unsigned comment added by 71.85.231.55 (talk) 16:56, 13 March 2015 (UTC)

Some More Interesting Facts About Years With Three Fridays the 13th
Three years before and after a year with three Fridays the 13th, those years will always have three Fridays the 13th as well. This also reminds me of one of Henry Dudeney's problems in his book "536 Puzzles and Curious Problems." Problem 528, "A Leap Year Puzzle," says "The month of February in 1928 contained five Wednesdays. There is, of course, nothing remarkable in this fact, but it will be found interesting to discover the last year prior to 1928 and the first year after 1928 that had five Wednesdays in February." Nothing remarkable, other than the fact that such a year will contain three Fridays the 13th. Finally, an American President whose second term commences on January 21 (because January 20 was a Sunday) will serve as President during three years with three Fridays the 13th. Ronald Reagan, for example, served as President during all three Fridays the 13th in 1981, 1984, and 1987. The previous year with three was 1970 and the next year with three was 1998. Neither Reagan's predecessor nor successor could have served as President in a year with three Fridays the 13th. — Preceding unsigned comment added by 76.229.246.81 (talk) 16:15, 29 May 2015 (UTC)
 * The first statement is true when one starts with a leap year starting on Sunday. For common years starting on Thursday, three years before can be:
 * A leap year starting on Sunday (e.g. 2012/2015)
 * A common year starting on Sunday (e.g. 2006/2009 and 2023/2026)
 * A common year starting on Monday (twice every 400 years: 2198/2201 and 2300/2303)
 * and three years after can be:
 * A leap year starting on Sunday (e.g. 2009/2012)
 * A common year starting on Sunday (once every 400 years: 2099/2102)
 * A common year starting on Monday (e.g. 2015/2018 and 2026/2029)

Clarification on Italians within this article
Under History it is stated that there is an early document in English referring to Friday the 13th and it states that "like so many Italians, he regarded Fridays as an unlucky day and thirteen as an unlucky number"

Yet within the section of Italians and the number 17 it states that Italians consider the number 13 to be, in fact, lucky - not unlucky.

Over an appropriate span of years, the 13th occurs exactly the same number of times on each day of the week
What I say below contradicts the conclusions of the author of the section in question. Therefore, I submit it for review. If a consensus of administrators agrees with me, then either I or, preferably, the original author can make the appropriate changes to the section.

In the section “Occurrence” the first paragraph (below the large table) begins: “This sequence, given here for 1900–2099, follows a 28-year cycle from 1 March 1900 to 28 February 2100.” The rest of the section then shows how “[t]he 13th day of the month is slightly more likely to be a Friday than any other day of the week.” I believe that this conclusion is incorrect, however, being solely the result of the choice of 200 years as the time span to be examined. It would also have been incorrect if the chosen time span had been 400 years.

The writer mentions the 28-year cycle but then ignores the crucial fact that in any 28-year cycle, each of the 365 common days (including each 13th) falls exactly four times on each day of the week. Since there are seven days in a week, each common day (including each 13th) occurs 7 × 4 = 28 times in 28 years (as it should), for a total of 28 × 365 = 10220 days; February 29 occurs seven times in 28 years, once on each day of the week. Thus in 28 years there ordinarily are 10227 (10220 + 7 = 10227) days.

This pattern holds for all spans of years that are integer multiples of 28 years and only for spans that are integer multiples of 28 years. It does not, therefore, hold for 200 years or for 400 years because neither is an integer multiple of 28 years (200 ÷ 28 = 7.14285714...).

On the other hand 420 years (or 392 years, and so on) is an integer multiple 28 years (420 = 15 × 28). Thus in 420 years the 13th of a given month falls on a Friday exactly 15 × 4 = 60 times, and the 13th of that month also falls exactly 60 times on each of the other six days of the week, as well. Thus the 13th of that month occurs 7 × 60 = 420 times in 420 years (as it should). The same is true for each of the 365 common days (including each of the other 13ths) giving a total of 365 × 420 = 153300 common days in 420 years. Adding in the nominal 105 occurrences of February 29 gives a total of 153300 + 105 = 153405 days in 420 years, which is exactly equal to 15 cycles of the 10227 days in 28 years (15 × 10227 = 153405).

To be perfectly accurate there are really only 153402 days in 420 years. That is because three of the four century years spanned have only 365 days, not 366. That means, as well, that three of the fifteen 28-year cycles (three of the four cycles that include a century year) have only 10226 days. Thus, recalculating, there are 12 cycles × 10227 = 122724 days and 3 cycles × 10226 = 30678 days for a total of 122724 + 30678 = 153402 days, which is the same as the true number of days in 420 years.

In addition, in 420 years there are 5040 months (420 × 12 = 5040). As said above, the 13th of a given month falls on a Friday exactly 60 times in 420 years. Since there are 12 months in every year, that means that there are 12 × 60 = 720 Friday the 13ths in 420 years. And, by the same reasoning, there are also 720 Thursday the 13ths and 720 Wednesday the 13ths, and so on. Since there are seven days in a week, the total number of 13ths in 420 years is 7 × 720 = 5040, which, as above, is exactly the number of months in 420 years.

The correct conclusion, therefore, is that in any span of 28 years or integer multiple of 28 years the 13th falls on each day of the week exactly the same number of times as it falls on every other day of the week. But that correct conclusion can only be reached by examining a number of years that is exactly an integer multiple of 28. In other words, by choosing to examine only multiples of 28 years, we discover that the 13th occurs on Friday exactly the same number of times as it occurs on every other day of the week.

If, for example, we examine 1200 × 28 years = 33600 years, we find the 13th of any given month occurring exactly 1200 × 4 = 4800 times on a Friday and also 4800 times on each of the other six days of the week, as well. Thus the 13th of each month occurs 7 × 4800 = 33600 times in 33600 years (as it should). (It is irrelevant and inconsequential that we are here not making the correction for the 252 century years that would have only 365 days instead of the 366 that otherwise occur every fourth year.)

And so it is misleading and leads to an incorrect conclusion to use a span of 400 years as the test span for deciding whether the 13th occurs on a Friday more often than it occurs on other days of the week. That number of years (400) is not evenly divisible by 28; the number is important only because, by adjusting the span of 400 years to have exactly 146097 days, we are easily able to keep the first day of spring close to March 21 over a span of many centuries before a more precise correction has to be made. The choice of 400 years had nothing to do with determining how many times the 13th fell on a Friday, as opposed to any other day. The choice of 400 years was made because it provided a convenient and simple rule-based calendar that was more accurate than the widely used Julian calendar.

In sum, only if you examine a span of years that is an integer multiple of 28 do you draw the correct conclusion that the 13th day of the month is exactly as likely to occur on a Friday as on any other day of the week. Wikifan2744 (talk) 01:46, 18 May 2016 (UTC)
 * No, skipped leap days in century years do cause 28-year intervals to not have exactly 48 Friday the 13ths.

History section quotes Henry Sutherland Edwards saying "like so many Italians, he regarded Fridays as an unlucky day and thirteen as an unlucky number" but then "Friday the 17th in Italy" section says "In fact, in Italy, 13 is generally considered a lucky number" and cites

Where the quote from Edwards appears, please note that the Edwards was incorrect in saying that Italians regard 13 as unlucky and cite the same source as in the section about the 17th. 47.139.45.162 (talk) 04:00, 13 September 2019 (UTC)

List the horror films released then?
Since it is common for horror films to be released on Friday the 13ths throughout the years, should there be a list of those films in this article? If it is simply dismissed as trivia, then I guess it isn't important.

Friday the 13th
I was watching the history channel and they stated Friday the 13th unluckiness can be traced back to the Freemason's and Knights Templar when the Pope of that time ordered them to be slaughtered on Friday the 13th.65.155.99.58 (talk) 17:36, 13 August 2021 (UTC)

Knights Templar kill order
Didn't the Pope issue a secret assassination order against them to be executed on Friday the 13th? 148.168.122.20 (talk) 20:10, 13 May 2022 (UTC)

I thought so too. But looking further apparently this is a myth spread by the History channel. Ken L (talk) 21:34, 13 May 2022 (UTC)

The Knights Templar
The Knights Templar were supposedly captured and killed by the church as ordered by the Pope at the time. Because they were becoming too rich and powerful influencing important people. 2601:281:C080:1E90:2C3D:BA59:D7F:4357 (talk) 00:03, 14 May 2022 (UTC)

The origin section is misleading
Why is this article protected so it cannot be added to and corrected? At the moment the origin section is very weak/erroneous. It is based on the assertion of one so-called folklorist who is not a folklorist but an amateur who also doesn't seem to know much about Norse myth. If you believe him then 1. which Norse text are we talking about 2. where is the evidence that Medieval Scandinavians thought 13 was unlucky? Link it then to the appropriate article on the Norse text in question. But I can tell you that if it's referring to Lokasenna it is wrong. Baldr was not killed during the events of Lokasenna and there was not just 13 named people present at that feast. (Or is it supposed to come from Gylfaginning, which gives the most complete version of Baldr's death but which isn't about a feast?) Lokasenna did not take place on Friday 13th either. So here we are conflating the issue - that 13 at a feast (ie the number) = unlucky but that doesn't tell us why Friday 13th is unlucky. Going back to the Christian origin - there is no evidence that people thought the numbers at the last supper were unlucky for most of history and for good reason. It is not certain there were 13 people at the last supper. Mark’s gospel indicates Jesus asked two disciples to prepare the Passover meal and then Jesus “came with the Twelve” (Mark 14:13-17). According to Mark’s gospel, at least fifteen people attended the Last Supper: Jesus, two disciples and “the Twelve”. The idea of 12+1 is most likely from paintings eg Da Vinci et al. We don't need to argue any of this, but merely note that 13 has been considered an unlucky number and link to the article on the number 13 which goes through much of this.

The next question is why is a Friday unlucky? Likely this is its associations with goddesses/paganism. eg here are mentions of unlucky Fridays in literature eg Chaucer said Friday was a day “of misfortune”. Robert Greene coined the expression “Friday-face,” (1592) which meant a look of gloom or dismay. William Rowley (1633) in A Match at Midnight described “A plague of Friday mornings — the most unfortunate day in the whole week.” Richard Flecknoe - “Now Friday came, you old wives say, Of all the week’s the unluckiest day.”

Then how/when did the two unlucky things be put together? The "tradition" of Friday 13th appears to be a much later one which has been post-justified with examples throughout history. The evidence points to a 19th or 20th century origin eg Thomas Lawson’s (1907) book - Friday, the Thirteenth. Nathaniel Lachenmeyer wrote a whole book on this where he argued that before the 20th century, “13” had been an unlucky number, and “Friday” had been an unlucky day, but “Friday the 13th” wasn’t a concept.

In terms of unlucky events on Friday 13th used as justification, you should definitely mention St Brice's Day Massacre (1002AD) and link to that article. You should also mention that feminists are rehabilitating Friday 13th and the number 13. (eg note Taylor Swift's comments about it) SandrinaHatman (talk) 10:46, 31 May 2022 (UTC)

Origin section confuses reliable sources with speculation
The Origin section confuses speculations about the origin, from the earliest documented source, which is Edwards, H. S. (1869). The Life of Rossini, and which is problematic, because French and German wikis say that Italian unlucky day is Tuesday the 13th; Italian is one language that does not have a wikipedia article for this item. Donald Dossey apparently counseled many people with phobias, but he is not a specialist in Scandinavian mythology and his claim that the "origin" is a banquet of 12 gods in Valhalla intervened by a 13th is ignored by all the Scandinavian wikis (instead, they tend to point to St Brice's Day massacre); obit: <https://www.legacy.com/us/obituaries/citizen-times/name/donald-dossey-obituary?id=16901160>. There needs to be two sections: first, Origin historically documented instances of the superstition as a superstition; followed by a completely separate section Explanations: speculations about the origin. Can even a single almanac be cited? Is the superstition a creation of the age of Gothic novels? Vagabond nanoda (talk) 08:59, 28 August 2022 (UTC)

Friday the 13th in Italy

 * «due to Americanization, young people consider Friday the 13th unlucky as well»

Actually, the source just states «Friday the 13th is an unlucky day» («Venerdì 13 è un giorno che porta sfortuna») in its title, so it is neither a statement from one (just one) young person nor anything connected to Americanization.

The article states rather that, in Italy, weddings and departures are traditionally forbidden on Friday and Tuesday («di Venere e di Marte non si sposa e non si parte»). Number 13 is regarded as unlucky when sitting together on lunch/dinner, because of the Last Supper (one died) --Actormusicus (talk) 12:00, 10 January 2023 (UTC)

I don’t think this should be a day of bad luck
I don’t think so because only god can decide a day of bad luck and a day of death so you should not believe in this day as bad luck! 97.64.245.82 (talk) 21:34, 12 January 2023 (UTC)
