Usage
Register the package at the ZCA via ZCML:
<include package="icemac.recurrence" />
Compute recurrences. The example computes the 2nd Tuesday each month.:
>>> from icemac.recurrence import get_recurrences >>> get_recurrences( ... datetime=datetime(2015, 10, 13, 11, 15), ... period='nth weekday of month', ... interval_start=datetime(2015, 1, 1), ... interval_end=datetime(2015, 12, 31)) [datetime(2015, 10, 13, 11, 15), datetime(2015, 11, 10, 11, 15), datetime(2015, 12, 8, 11, 15)]
Supported recurrence periods:
daily
weekly
biweekly
nth weekday of month
nth weekday every other month
nth weekday from end of month
nth weekday from end of other month
yearly

Changelog
1.2 (2016-04-16)
Fix handling for dates with a timezone which has a daylight saving time (DST): The local time of the recurrence does not change when switching DST though the UTC representation of the time will now change.
1.1 (2016-03-01)
Shorten the import path of get_recurrences() from icemac.recurrence.recurrence to just icemac.recurrence.
Refactor tests to use py.test fixtures.
Fix an off by one month error in the periods nth weekday every other month and nth weekday from end of other month.
Bring the test coverage to 100 % even in branch coverage.
1.0.1 (2015-10-22)
Fix broken 1.0.0 release.
1.0.0 (2015-10-13)
