Dateutil

Last updated:

The dateutil module provides powerful extensions to the standard datetime module.

Install ​

shell
pip install python-dateutil

Usage ​

python
from dateutil import tz, parser
from dateutil.relativedelta import relativedelta

Getting a timezone:

python
UTC = tz.tzutc()  # tz.gettz('UTC')
JST = tz.gettz('Asia/Tokyo')

Parsing a date automatically:

python
mydate = parser.parse('2018-04-30T06:37:10.751Z')

Incrementing months is very easy with relativedelta, because it automatically deals with edge cases like months with different quantity of days.

python
datetime(2021, 1, 31) + relativedelta(months=1)  # February 28th
