Don't trust it, even if it exists; test carefully to determine whether
it gives the sort of week number that you need, and whether it does so
correctly.

There is an International Standard which includes week numbering, ISO
8601, and it is in general use world-wide. Except, of course, in
America, where they use a number of other forms of week-numbering.

I have Pascal/Delphi code to calculate the ISO week number from the
date, in dateprox.pas, uses version.pas, tested by mjd_date.pas, all via
sig line 3 below. See also

Anything that gives the ISO week number needs also to return the Year
Number, and may well return also the day-of-week.
