Oops...forgot to add what you want.
%U The week number of the current year as a decimal number,
range 00 to 53,
starting with the first Sunday as the first day of week 01.
See also %V and
%W.
And this one:
%V The ISO 8601:1988 week number of the current year as a decimal
number, range
01 to 53, where week 1 is the first week that has at least
4 days in the
current year, and with Monday as the first day of the week.
See also %U and
%W. (SU)
But SQLite doesn't implement those.

Subject: [sqlite] First Day of Week Inconsistency
The built-in function strftime properly (imho) responds to the '%w' command
for day of week with Sunday as day 0.
e.g. - strftime ('%w','2013-06-19')
-> 3
But the built-in function for returning week of the year treats weeks as
though they begin on Monday, not Sunday:
e.g.
strftime ('%W','2013-06-19')
-> 24
strftime ('%W','2013-06-17')
-> 24
strftime ('%W','2013-06-16')
-> 23
It seems to me these useful functions are inconsistent. Is it possible to
modify %W to treat Sunday as the first day of the week?
Thanks,
Denis Burke
