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
