1) A timedelta object denotes a duration, it can also represent the difference between two dates or times.

We can use this object to add to or subtract a duration from a date, and it defines its constructor as datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)

It is used in python3 to add/subtract date :

# Timedeltafunction demonstration   from datetime import datetime, timedelta     # Using current time ini_time_for_now = datetime.now()   # printing initial_date print ("initial_date", str(ini_time_for_now))   # Calculating future dates # for two years future_date_after_2yrs = ini_time_for_now + \                         timedelta(days = 730)   future_date_after_2days = ini_time_for_now + \                          timedelta(days = 2)   # printing calculated future_dates print('future_date_after_2yrs:', str(future_date_after_2yrs)) print('future_date_after_2days:', str(future_date_after_2days)) 2) python3 time zone first specify time zonein settings.py for your project TIME_ZONE = 'Europe/Brussels' USE_TZ = True in your views, from django.utils import timezone timezone.now() will give you UTC time at the moment for the timezone specified in settings.py to get your timezone for the time at moment use : timezone.localtime(timezone.now()) https://stackoverflow.com/questions/39953166/django-utils-timezone-now-returns-utc-in-default-timefield
