time/py-dateutil - The NetBSD Packages Collection

The `dateutil` module provides powerful extensions to the standard `datetime`
module, available in Python.

Features

* Computing of relative deltas (next month, next year, next monday, last week
  of month, etc);
* Computing of relative deltas between two given date and/or datetime objects;
* Computing of dates based on very flexible recurrence rules, using a superset
  of the iCalendar specification. Parsing of RFC strings is supported as well.
* Generic parsing of dates in almost any string format;
* Timezone (tzinfo) implementations for tzfile(5) format files
  (/etc/localtime, /usr/share/zoneinfo, etc), TZ environment string (in all
  known formats), iCalendar format files, given ranges (with help from
  relative deltas), local machine timezone, fixed offset timezone, UTC
  timezone, and Windows registry-based time zones.
* Internal up-to-date world timezone information based on Olson's database.
* Computing of Easter Sunday dates for any given year, using Western, Orthodox
  or Julian algorithms;
* More than 400 test cases.
