Talk:1800

untitled
I have made some year layout proposals which would affect a significant proportion of the year pages: an example of proposed style is 1850. It is detailed on my talk page.

If no-one flags where I have put the discussion on my talk page that they object in a month I will start making everything consistent. It may take some time... --BozMo 10:46, 7 May 2004 (UTC)(talk)

Should the reference to "27 June - Pascha Jussuf Karamanli of Tripoli declares war on Sweden by having the flagpole on the consulate chopped down." actually be a declaration of war with the United States. The article on Pasha Jussuf certainly seems to suggest so. If thi isn't an innacuracy then perhaps the declaration against the united states should also be added. -[Piersy 14:12, 1 June 2006]

Births, section 2.2

Leap Year?
The pages for Leap Year and Century Leap Year say that 1800 was not a leap year. This page says it was. — Preceding unsigned comment added by 50.200.93.68 (talk) 18:27, 4 February 2015 (UTC)

9 days in February
If the year is divisible by 200 but not by 400, then February has 9 days and there is 346 days in a year.

February 9, 1800 (a valid date)

February 10, 1800 (an invalid date)

So the day after  would be   rather than.

February 29th only occurs in leap years, where as February 10th through the 28th occurs every year unless if the year is divisible by 200 but not by 400.

1800, 2200, 2600, 3000, 3400, 3800, 4200, 4600, 5000, 5400, and 5800 will have 9 days in February

1700, 1900, 2100, 2300, 2500, 2700, 2900, 3100, 3300, 3500, 3700, 3900, 4100, 4300, 4500, 4700, 4900, 5100, 5300, 5500, 5700, and 5900 will have 28 days in February

1600, 2000, 2400, 2800, 3200, 3600, 4000, 4400, 4800, 5200, 5600, and 6000 will have 29 days in February

So the day after February 9, 2200 will be March 1, 2200. --98.31.29.4 (talk) 16:10, 1 August 2019 (UTC)

1800
1800 (MDCCC) was an exceptional common year starting on Wednesday of the Gregorian calendar and a leap year starting on Sunday of the Julian calendar, the 1800th year of the Common Era (CE) and Anno Domini (AD) designations, the 800th year of the 2nd millennium, the 100th and last year of the 18th century, and the 1st year of the 1800s decade. As of the start of 1800, the Gregorian calendar was 11 days ahead of the Julian calendar, which remained in localized use until 1923. 190.213.232.105 (talk) 05:17, 10 December 2022 (UTC)

why exceptional?

 * Hello. An exceptional common year is any year divisible by 100 (thus by 4), but not by 400. --NicoScribe (talk) 21:22, 6 October 2023 (UTC)
