Convert timedelta to datetime Object in Python (Example)


In this Python tutorial you’ll learn how to convert timedelta objects to datetime objects.

The tutorial consists of one example for illustrating the transformation from timedelta objects to datetime objects. The content of the tutorial is structured as follows:

So now is the part you have been waiting for!


Example Data & Imported Modules

For this example, we need to import the datetime module and define a timedelta object, which is td in this case.

import datetime                                       # Loading datetime module
td = datetime.timedelta(days=45, seconds=500000)      # instantiating timedelta object
print(td)                                             # printing the timedelta object
# 50 days, 18:53:20

As seen in the previous output, td is formatted by the print() function automatically.

Let’s create an example now!


Example: Converting timedelta to datetime

Since timedelta objects refer to the diffference between two datetime objects, we need another datetime object as a reference. It is defined under the name dt_origin as follows.

dt_origin = datetime.datetime(1995, 5, 1, 14, 15, 3)  # instantiating origin datetime object
print(dt_origin)                                      # printing the datetime object
# 1995-05-01 14:15:03

Now we are ready to implement the conversion!

dt_new = dt_origin + td                               # generating a datetime from timedelta object
print(dt_new)                                         # printing the generated datetime object
# 1995-06-21 09:08:23

  • I’ve never commented anything in my whole life but i have to say this is the worst article that i have ever seen.
    I’m even losing time to write this comment because your article doesn’t show anything AT ALL and yet it is still indexed as a relevant source to convert a timedelta to datetime.

    Next time if you take time to write an article, actually show what you wrote as a title instead of doing nothing.
