Question

How can I subtract or add 100 years to a datetime field in the database in Django?

The date is in database, I just want to directly update the field wit

Answer 1

Use timedelta. Something like this should do the trick:

import datetime
years = 100
days_per_year = 365.24
hundred_years_later = my_object.date + datetime.timedelta(days=(years*days_per_year))
