I would like to show a minor view of mine on writting of today's dates. I am fully awared with ISO 8601 standard. Recently I prefer to writte dates in these Mayan like form.
For example dates of current week I write:
0 Sunday [2002.02.24] 1 Monday [2002.02.25] 2 Tuesday [2002.02.26] ... 6 Saturday [2002.03.02]
It is strange, yes - but ISO 8601 in a sence goes the same way. Mayan have two weeks with different number of days and I know why they write in such strange form which is, astronomically speaking, perhaps the best and the righteous one. We have only one week, with 7 days, first would be numbered as Mayan do 0. And all in brackets ([]) is noncycleing but linear increasing numbers for years, set of 12 months with selection from {28,29,30,31} and of course in the end - days all numbers in decimal system. Mayan used kindly different number systems. How long will it take we will adopt ISO 8601 in fully. I am sometime nowadays all confused. What do you think?
XJam following ISO 8601 let us write just 2002-27-02 where leading zeroes must be written. ** This is not ISO !! ** *** Yes you gotcha me, of course 2002-02-27 is correct - that is what I was talking about -- confusions, sorry --XJam 6 Saturday [2002.03.02] (0)***
So one can start the week on a Sunday, but number the other days of the week by the number of days it comes after Sunday.
Sunday 0, Monday 1, Tuesday 2, Wednesday 3 Thursday 4, Friday 5, Saturday 6.
This looks like a compromise between starting the week on Sunday (actual start) and starting the week on Monday (numbering of non-Sundays).
If one starts with week with a Sunday then a symmetry occurs around the year 2000.
Below for each year, I list the number of days in the part-week at the start of the year, the number of whole weeks within the year, then the number of days part-week at the end of the year.
1997 4 days + 51 weeks + 4 days 1998 3 days + 51 weeks + 5 days 1999 2 days + 51 weeks + 6 days 2000 1 day + 52 weeks + 1 day 2001 6 days + 51 weeks + 2 days 2002 5 days + 51 weeks + 3 days 2003 4 days + 51 weeks + 4 days
This symmetry applies to all years not just those listed e.g.
1900 6 days + 51 weeks + 2 days
2100 2 days + 51 weeks + 6 days
For weeks beginning Monday or any other day of the week, there is no such symmetry around any year at all.
Yes I have understood that correctly. Thank you Karl for clearing this out. This year's 2002 first part-week is:
[2] Tuesday [2002.01.01] [3] Wednesday [2002.01.02] [4] Thursday [2002.01.03] [5] Friday [2002.01.04] and the last day of the 1st part-week [6] Saturday [2002.01.05] --> and all together is 5 days.
Then we have 51 "ordinary" weeks and the last part-week:
[0] Sunday [2002.12.29] (First day of the last part-week :-) [1] Monday [2002.12.30] and finally [2] Tuesday [2002.12.31] --> that gives us 3 days
so 2002 have: 5 + 51*7 + 3 = 365 days.
Nice. --XJam 1 Monday [2002.03.04] (0)

Strange property of Gregorian calendar, don't you think and hard to calculate days between events in it, too. On my desk working calendar there is written that 2002 has 52. working weeks (fixed day (or closing date) weeks again according to ISO 8601) and 1st working week of 2003 starts on 1 Monday [2002.12.30]. 1st working week of 2002 starts again on 1 Monday and that is [2001.12.31]. In fact I do not like Gregorian calendar a lot, but I must use it. Tzolk'n is much much more thoughtful and who knows more usefull. I do not like Gregorian calendar too because astrologists calculate their strange horoscope and fated tables from it, and they say they're some experts on something that doesn't exist, astronomicaly speaking. (I mean a sky map, which because of precession of equinoxes does not fit with a real one and such). --XJam 5 Friday [2002.03.01] (0)
Astrologers would may also get it wrong if they use the Gregorian calendar literally. For example the start of the sun-sign of Aries is reckoned to occur at at the March equinox and also on March 21, yet in 2096, the equinox will be on March 19. --User:Karl Palmen
In Japan, all official documents are required by law to use the Japanese imperial calendar date format. For example, the year 2001 is known as Heisei 13 (平成13年). Similar, in Taiwan, the year 2002 is known as Min-guo 91 (民國九十一年).
What about giving an example of one of the dates from the period when the calendar was being adopted and the new year shifted (from March to January), resulting in year formats such as 1680/81, to mean 1680 if new year is counted in March, but 1681 if new year is counted in January ?

Is there any usage of ISO8601 while writing long date format. I know that ISO concerns only in numeric representation.
The internet has allowed date formats similar to other nations is diffusing one after another. Examples of these include some of the "American format" talk in other countries, the date appearaing occasionally before the month in the US has somewhat increased, and use of a period in endian forms as a separator in the U.S. as of late (such as CBS Evening News, The Today Show, FOX News, and the Baltimore Sun newspaper, many recent films.) The month day year format stil exists though. Some confusion, especially on international english websites like Youtube, lead to some confusion, especially on the first 12 days of every month. Maybe a separate section could discuss this influence.
