Examples

The default is to print Tuesdays and Thursdays for 14 weeks, starting on the current day. e.g. if run on Jan 22, 2018 with the default arguments:

$ ./days.py
Tue Jan 23
Thu Jan 25
Tue Jan 30
Thu Feb  1
Tue Feb  6
Thu Feb  8
Tue Feb 13
Thu Feb 15
Tue Feb 20
Thu Feb 22
Tue Feb 27
Thu Mar  1
Tue Mar  6
Thu Mar  8
Tue Mar 13
Thu Mar 15
Tue Mar 20
Thu Mar 22
Tue Mar 27
Thu Mar 29
Tue Apr  3
Thu Apr  5
Tue Apr 10
Thu Apr 12
Tue Apr 17
Thu Apr 19
Tue Apr 24
Thu Apr 26

Here, we print 4 weeks of Wednesdays starting on Jan 15, 2018.

$ ./days.py -y 2017 -m 1 -d 15 -w 4 -s Tue Thu
Tue Jan 17
Thu Jan 19
Tue Jan 24
Thu Jan 26
Tue Jan 31
Thu Feb  2
Tue Feb  7
Thu Feb  9

Print Fri, Sat, Sun for three weeks, but also group the output in chunks (-c).

$ ./days.py -s Fri Sat Sun -w 3 -c
Fri Jan 26
Sat Jan 27
Sun Jan 28
----------
Fri Feb  2
Sat Feb  3
Sun Feb  4
----------
Fri Feb  9
Sat Feb 10
Sun Feb 11
----------

Why?

I sometimes teach a class and find it hand to have a list of dates. I also haphazardly put this together over several months without ever thinking about looking at any other tools ¯\_(ツ)_/¯.
