Answer 1

You could take a look at datetime.datetime.dayofweek() but if you are not allowed to use an external library then you need to:

1. pick a date that you know the day of week of - best if it is a Monday
2. come up with a formulae for the number of days since then that the first of a given month is.
3. for each of the days in the month the (number of days since your day) % 7 in [5, 6] is a weekend.
