This depends on what your source means by the week number. Is week 01 the week
starting on January 1 (so that the starting day of the week changes from year
to year)? the week including January 1 (even if that's the Saturday at the end
of the week)? The week containing the first Wednesday of the year? or what?

You can get a "rough cut" using an expression

DateAdd("ww", Right(yourfield, 2), DateSerial(Left(yourfield, 4), 1, 1))

using DateSerial to get the January 1 date in that year and DateAdd to add
that many weeks to that date, but the answer will be incorrect if your
definition of a week number differs from the one Access assumes.
