 # python-tz
 
+pytz brings the Olson tz database into Python.
+This library allows accurate and cross platform timezone calculations using Python 2.3 or higher.
+It also solves the issue of ambiguous times at the end of daylight savings, which you can read more about in the Python Library Reference (datetime.tzinfo).
