Talk:ISO week date
From Wikipedia, the free encyclopedia
Ok, I understand now "What if most years had a leap week?". What matters for the maximum change of corresponding equinoxes between two years is the largest deviation of a year from the average year.--Patrick 21:38, 30 May 2006 (UTC)
[edit] Use of term "Leap Week"
I have seen ISO 8601:2000 but not ISO 8601:2004. ISO 8601:2000 does not use the term "leap week"; I don't know whether ISO 8601:2004 does.
Unless the term is introduced in ISO 8601:2004, it seems to me unwise to introduce it elsewhere; "week 53" suffices. It leads to using "leap year" for 53-week years, which clashes with conventional use. It might be thought to mean a week containing February 29th.
Re section "Disadvantages" : The ISO Week Calendar could fully replace the Gregorian, because it is possible to calculate Day 1 of a given year directly - but the expression will be more complicated.
Re section "Advantages" : Although the date of Easter Sunday would be no easier to calculate, the number of possible dates would be less, since all are Day 7. Only a few Week Numbers would be possible.

Only six Week Numbers, 12-17 would be possible, 17 being rare.
