Sounds like date's W is equivalent to strftime's %V which does indeed return "01" for this date as there's at least 4 days of the new year in that particular week. Both %U and %W seem to return what you want, using strftime. I'd guess that date would also have flags for these. Cheers, Geoff. -- Thanks Geoff, that's what I was looking for.
