datetime-interval

The builtin datetime module provides classes for points in time (date, and datetime) as well as durations (timedelta), but it does not account for time durations at a specific point. This module provides Interval, which contains a start and end date or datetime, and a duration timedelta. This is useful for representing calendar events. This module also provides PeriodicInterval which can be used for recurring events, by containing a period timedelta and a count of occurrences (either an int or forever).

TODO:

• Interval isoformat method (start/end).

  • This wouldn't work on PeriodicInterval, as recurring intervals have a different semantics in ISO 8601.

• Property-based testing with props

• Add operators for PeriodicInterval (*, [])

• How to account for e.g. every Tuesday and Thursday
