Ahmed Bouchefra: Add days to dates in Python

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 datetime module.

For example:

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:

>>>fromdatetimeimportdatetime,date,timedelta>>>today=datetime.today()>>>print(today+timedelta(days=1))2022-09-3020:42:58.812066

The 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))2022-10-0100:00:00

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 timedelta() class.
