Yes, exactly. This is officially defined in ISO 8601:1988 and
subsequently used by POSIX.2-1922 and by ISO C '99.
I quote from the GNU C Library manual:
ISO weeks start with Monday and end with
Sunday. Week `01' of a year is the first week which has the
majority of its days in that year; this is equivalent to the
week containing the year's first Thursday, and it is also
equivalent to the week containing January 4. Week `01' of a
year can contain days from the previous year. The week
before week `01' of a year is the last week (`52' or `53') of
the previous year even if it contains days from the new year.

I don't know the definition but it apears that the week starts on
Monday.
date --date='28 Dec 2003' +%V
52
date --date='29 Dec 2003' +%V
01
Since it is a "work week" usage that makes perfect sense to me. Work
weeks start on Monday to most industry.
