Disambiguation link notification for March 4
Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Austin K2/Y, you added links pointing to the disambiguation pages Britain, Lapland and Hardway (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ* Join us at the DPL WikiProject.

Station X
I undid your edit to Bletchley Park, because I read recently that there is no evidence that the X means 'ten'. There wasn't a Station IX or Station VIII. But if you can find a reliable citation for 10, please reinstate. --John Maynard Friedman (talk) 18:03, 22 January 2015 (UTC)

Your edits in "Computus"
Hallo,

Please be aware that your new Excel formula does not support the optional 1904 date system. The DAY function helps to handle the differences between the 1900 and 1904 date systems. So it is possible to get universal formulas for both date systems Frank Schneider 85.199.76.86 (talk) 11:36, 1 July 2017 (UTC)

Frank,

Thank you. I have corrected the formula now. sigurdhu (talk) 16:35, 26 July 2017 (UTC)

Hallo Sigurd, sorry for chasing you, please test it again, the last one does not work in the 1904 system, some years have wrong results. With the 1900 date system one part DATE(A1,3,27) is OK With the 1904 date system this part has to be DATE(A1,3,26) to get always the correct result For unification, you can use DATE(A1,3,27-DAY(0)) or DATE(A1,4,-DAY(4)) Frank Schneider 85.199.76.86 (talk) 09:14, 20 August 2017 (UTC)

Frank,

Thanks again. Obviously I had not tested the formula thoroughly. I have now corrected the formula so it works for all dates in the 1904 date system too. sigurdhu (talk) 07:08, 21 August 2017 (UTC)

Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Determination of the day of the week and Quadratic formula, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. DVdm (talk) 16:05, 31 January 2021 (UTC)
