HTML Calendar Generator

There is probably a ton of these already, but here is my contribution, based on my personal preferences. I prefer to have week numbers on my calendars, and that the week starts on Mondays. The output is in a 4x3 month format, suitable for printing on a A4 sized landscape oriented paper.

Here is the Python script:

#!/usr/bin/python

import calendar
import datetime
import sys

if len(sys.argv) > 1:
    try:
        year = int(sys.argv[1])
    except ValueError:
        sys.exit(1)
else:
    year = datetime.date.today().year
