python – Parsing crontab-style lines
python – Parsing crontab-style lines
Perhaps the python package croniter suits your needs.
Usage example:
>>> import croniter
>>> import datetime
>>> now = datetime.datetime.now()
>>> cron = croniter.croniter(45 17 */2 * *, now)
>>> cron.get_next(datetime.datetime)
datetime.datetime(2011, 9, 14, 17, 45)
>>> cron.get_next(datetime.datetime)
datetime.datetime(2011, 9, 16, 17, 45)
>>> cron.get_next(datetime.datetime)
datetime.datetime(2011, 9, 18, 17, 45)
Maybe you can use this module:

I used that module for making an user-space cron in Python and it works very well. This module can handle crontab-like lines.
