In this example, we’ll see how to add days to dates in python.
To add days to a date in python, you simply need to use the
timedelta() class that you should import from the
dateplustwo = aDate + timedelta(days=2).
We passed a days argument to the
timedelta class and added two days to the date.
Here is the complete working example:
>>> from datetime import datetime, date, timedelta >>> today = datetime.today() >>> print(today + timedelta(days=1)) 2022-09-30 20:42:58.812066
datetime.today() method returns the current local datetime.
This can also be used with
date instead of
datetime as follows:
>>> today = date.today() >>> print(today + timedelta(days=3)) 2022-10-02
The date.today method returns a date object that represents the current local date.
Don’t forget to import the datetime or date and timedelta classes from the datetime module.
We can also use a date string but we first need to convert it a datetime object before adding days to it. Here is a working example:
>>> today = '2022-09-29' # format: yyyy-mm-dd >>> datetime.strptime(today, '%Y-%m-%d') datetime.datetime(2022, 9, 29, 0, 0) >>> print(today) 2022-09-29 >>> myday = datetime.strptime(today, '%Y-%m-%d') >>> print(myday + timedelta(days=2)) 2022-10-01 00:00:00
The datetime.timedelta class takes the days we need to add to the date or datetime objects.
We formatted the date string as
yyyy-mm-dd and we used the
strptime() method to convert the string to a datetime object, corresponding to the provided format, that we can use with the
