Working with Date and Time

Dateutil provides extensions to the methods already available in datetime and includes features for processing raw data.

Dateutil is divided into several subclasses:

• easter — used to calculate the date and time based on different calendars, specifically: Western, Orthodox, and Julian.
• parser — includes an advanced date and time parser, allowing us to parse various formats.
• relativedelta — designed for replacing components of a date.

Additionally, it's worth mentioning utils, which contains basic functions for working with date and time.

from datetime import datetime
from dateutil.relativedelta import relativedelta

# Current time

dt_now = datetime.now()
print(dt_now)

# Next month

print(dt_now + relativedelta(months=+1))

# Next month, plus two weeks, at 13:00.

print(dt_now + relativedelta(months=+1, weeks=+2, hour=17))

# Calculating age

birthday = datetime(2000, 1, 1, 1, 1)

print(relativedelta(dt_now, birthday))
