I searched the forum, and there are several posts that calculate the day of the week, but I can't find any that compute the week number for a given date.

Does anybody have an algorithm for this?

By the way, I'm talking about the week number in the Gregorian calendar, not that of ISO-8601. This also implies that the starting day of the week is Sunday, as used in the USA.
