Talk:Leap year

It's a leap year, it's Leap Day in my part of the world, thus I added a Leap Year entry. I'm hoping someone will come and add some Liberal Deceit to it. Rylon 03:49, 29 February 2008 (EST)

Computer dates
Julian date in computing (old style commercial stuff) was simply the date in format YYddd which made sorting into order really easy and most date calculations simple arithmetic. It also stores nicely into databases. There were date routines to convert from local formats dd/mm/yy mm/dd/yy etc to and from julian dates. 67.72.98.45 (talk) 18:58, 19 March 2010 (UTC)

Julian date in astronomy was, I think, begun as a way of making sense of historical dates which were given for a wide variety of calendars which didn't agree on when the new year would begin, much less the number of the year - was it year N in the reign of king so-and-so, or year M after such-and-such significant event in the local culture, or year 1, 2, 3 or 4 in the Xth Olympiad. Much later it was realized that for certain regularly recurring astronomical events new years and leap years only served to complicate the calculations about something which occurred after a certain number of days, so that just counting the number of days simplified things.

Lots of incorrect stuff being added
Am I missing some sort of in joke? 1.The length of the year is approximately 365.2422 days. If it were 365.2425, that would mean that the present scheme for leap years, (100-3) every 400 years, would be an exact fit. If it were 365.25 days, then the Julian calendar would be an exact fit. 2. The length of daylight on the equinoxes is slightly more than 12 hours because the sun is not a point (so the upper limb of the sun is above the horizon when the center of the sun is not), and refraction in the atmosphere makes the sun appear a bit higher than the geometrical calculation. 3. The plural of the Latin word "nox" is "noctia". The English plural of "equinox" is "equinoxes". TomS TDotO (talk) 12:59, 21 March 2010 (UTC)

Which one is Leap Year?
As something of a Leap Year fanatic of several decades' standing, I'm embarrassed I never realized that, due to the jumping-over-the-29th principle, we arguably have three times as many Leap Years as non-Leaps! &mdash; Unsigned, by: Jokerman / talk / contribs 23:40, 30 December 2010 (UTC)

Mission
Why? Тy Ahoy! 05:32, 18 July 2011 (UTC)
 * To waste server space.--Colonel Sanders (talk) 05:35, 18 July 2011 (UTC)
 * Why? So you can do something substantive rather than run around turning footnotes into references and making shitty categorizing decisions and absurdly wikilinking parts of proper names rather than the whole thing. That's why.  05:40, 18 July 2011 (UTC)
 * Woah, Andy! Anyway, he really lives up to the label of janitor that sysopship implies.--Colonel Sanders (talk) 05:44, 18 July 2011 (UTC)
 * In the sense that he uses a dirty rag to spread shit around the stuff he's supposed to be cleaning, then yes. 05:52, 18 July 2011 (UTC)
 * Perhaps he needs to go back to janitor school and learn how to go to the laundromat to clean his rags? I remember cleaning some broken redirects of his or something.--Colonel Sanders (talk) 05:58, 18 July 2011 (UTC)
 * Err, think you might have misinterpreted the question there, NR. It was "why" as in "why does this article exist when it's off mission?"  You seemed to be answering... well, I'm not sure what question you were answering.  ThunderkatzHo! 06:06, 18 July 2011 (UTC)
 * The question I was answering was "hey should I post a single word question instead of making an effort to figure out how to integrate something that's obviously not useless nonsense into the wiki or at least come up with some kind of rationale for proposing to delete it?" Sorry if that was unclear. 06:26, 18 July 2011 (UTC)
 * (EC)Because its interesting and not really so far off mission. A lot of people don't understand all the ins and outs about leap years and this is a nice summary.  Not only should this not be deleted, it should be commended as a worthy treatment of the subject matter.  DamoHi 06:28, 18 July 2011 (UTC)

I've added stuff on superstitions to get it more on mission, I remember i didn't like it when the janitors threatened to delete a dirty article after I'd worked hard to develop it and included a lot of dirty on mission material. please try to be nicer Ty as a lot of work went into that article.

Gregorian Calender-ites
Perhaps a list of places/groups still using the old calendar? Offhand - Mount Athos (either because they dislike the Pope in Rome, or so they can confuse the police after one of their regular fights - sometimes involving fire hydrants, or arguing whether the 'name of Jesus' is of itself holy), 'at least one place in the UK', and the Russian Old Believers. 212.85.6.26 (talk) 17:41, 18 July 2011 (UTC)

Factoid
There have been a couple of TV-detective dramas where a diary has been identified as fake because of an entry for '29 February 1900.' Anna Livia (talk) 15:52, 26 April 2019 (UTC)
