Sorta-kinda.

>>> import datetime
>>> today = datetime.date.today()
>>> monday = today - datetime.timedelta(days=today.weekday())
>>> wednesday = monday + datetime.timedelta(days=2)
>>> saturday = monday + datetime.timedelta(days=5)
>>> week = datetime.timedelta(days=7)
>>> next_wed = wednesday + week

You can mess around with that. If you want to find the beginning of
the year, you could start by using datetime.date(2017, 1, 1) instead
of today(), and then locate the previous Monday the same way.

So yes, all the information is available, but no, there's no easy way
to say "give me all the Saturdays in 2017". You'd have to iterate.
