%description
There are two date arithmetic traps in the Gregorian calendar:
1. Leap years. Problems arise when adding years to a February 29th gives a
   result in a non-leap year.
2. Variable number of days in months. Problems arise when adding months to a
   29th, 30th or 31st gives a result in a month where that day doesn't exist.
In both cases, datedelta changes the result to the first day of the next month.
This method gives consistent results provided periods are represented by
(start date inclusive, end date exclusive) — that's [start date, end date) if
you prefer the mathematical notation. This representation of periods is akin
to 0-based indexing, which is the convention Python uses.
For example:
* If someone subscribes for a year starting on 2020-02-29 inclusive, the end
  date must be 2021-03-01 exclusive. If it was 2020-02-28 exclusive, that day
  would be missing from the subscription period.
* If someone subscribes for three months starting on 2020-03-31 inclusive, the
  end date must be 2020-07-01 exclusive. If it was 2020-06-30 exclusive, that
  day would be missing from the subscription period.
Operations are always performed on years, then months, then days. This order
usually provides the expected behavior. It also minimizes loss of precision.
