The day that the ISO-week new year begins and whether it has 53 weeks is determined by the dominical letter as shown at <URL: http://www.eleves.ens.fr:8080/home/madore/misc/calendar.html#gregorian.computus.dominical >.

ISO-Week New Year
G Jan 1
F Dec 31
E Dec 30
D Dec 29
C Jan 4
B Jan 3
A Jan 2

In leap years only the first dominical letter is used to determine the new ISO-week year.
An ISO-week year has 53 weeks if and only if its dominical letter contains a D.

Comments will not appear until they have been reviewed by the moderator.

Deleting comments is not supported. Please think before you post.

HTML is not allowed in content or elsewhere (writing <foo> simply produces <foo> in the text).

To cite a URL, write <URL: http://somewhere.tld/ >, and it will be automatically made into a link. (Do not try any other way or it might count as an attempt to spam.)

Your email address will not appear to other readers. Use it if you wish to leave me (the moderator) a way of contacting you.

To leave a contact address for all readers, use the Web site address field (it can be a mailto: URI, e.g. mailto:my.email@somewhere.tld, if you do not have a genuine Web site).

You can use an optional (semi-secret) “identifier phrase” of your choice to avoid identity stealing: it will not appear except to the moderator, who can use it to detect obvious usurpations. Don't rely seriously on this, however.

Use the last field to enter any other kind of comments for the moderator's eyes only.
