Starting at line 190 shouldn't first_day be validated to ensure that it falls within the month?

# get daily stat from today and a month back first_day = last_day_of_month(today.year, today.month-1) last_day = datetime(today.year, today.month, today.day, tzinfo=utc)

Holy formatting, Batman!

Nice catch. Thanks for pointing that out. Right now I change the number of days to 28 days in the past (4 weeks) instead of using same day of the previous month. This value could be parameter in the trac.ini file in the future.
