Re: Determine Week in Year

Hi James,

Thanks for the info -- that's at least one tidbit for me today from this
list. Even if they don't follow the ISO standards, they'd still have to
adjust for the starting day of the week.

BTW, looking at my year 2000 calendar, 1 Jan 2000 was a Saturday, so it
looks like 14 Jan 2000 actually was in the 2nd week using the ISO standards,
and in the 3rd week if not using ISO.
