I was just proposing an alias for "week" it that clarifies what it is the week *of*. The rest of what you ask is already established in Temporal.pm.
1. week returns the week number in the ISO 8601 week calendar. You can find the spec by Googling, but in summary: a. weeks begin on Monday b. weeks are numbered 1 to 52 or 53 c. week 1 is the first week containing at least four days of the new calendar year 2. week-year returns the year number, based on boundaries defined by the above principle. For instance, week 1 of this year began on January 4th, 2010, so on January 3rd, 2010, "week-year" would still return 2009. These are the same values returned by the %V and %G strftime(3) conversion specifications, e.g. date +%GW%V on Unixlike systems. >> By analogy, I'd say week-of-year should work as well. > > Oof, is there a generally accepted for numbering weeks within a year? > A month's boundaries' always coincides with a day's boundary, but a > year only occasionally begins/ends on a week boundary.
