Thanks for the report, however, this is not a bug. Read 'info date' for
more details (which in turn come from the POSIX rules):
`%U'
week number of year, with Sunday as the first day of the week
(`00'...`53'). Days in a new year preceding the first Sunday are
in week zero.
`%V'
ISO week number, that is, the week number of year, with Monday as
the first day of the week (`01'...`53'). If the week containing
January 1 has four or more days in the new year, then it is
considered week 1; otherwise, it is week 53 of the previous year,
and the next week is week 1. (See the ISO 8601 standard.)
`%W'
week number of year, with Monday as first day of week
(`00'...`53'). Days in a new year preceding the first Monday are
in week zero.
In other words, according to each set of rules, Jan 2 (Monday) belongs to
week 1.
