Convert datetime to timedelta Object in Python (2 Examples)

 

This article shows how to convert datetime to timedelta in the Python programming language.

Let’s get started:

 

Creation of Example Data & Import of Modules

Firstly, we need to load the datetime module.

import datetime                                                                   # Loading the datetime module
dt1 = datetime.datetime(1990, 1, 15, 8, 25, 40)                                   # Generating sample datetime

 

Example 1: Convert datetime to timedelta Using a Constructor

In this section, I’ll illustrate how to generate a timedelta object with in-day time values. We can simply put the timedelta parameters into the timedelta constructor to achieve our goal.

td1 = datetime.timedelta(hours=dt1.hour, minutes=dt1.minute, seconds=dt1.second)  # timedelta construction
print(td1)                                                                        # printing timedelta
# 8:25:40

 

Example 2: Convert datetime to timedelta via Subtraction

Example 2 illustrates how to do the conversion between two datetime objects via subtraction. As the subtraction between two datetime objects returns a timedelta object, we can construct a second datetime object with the same date and with 0 hours, minutes and seconds. By subtracting the new object (dt2) from the old one (dt1), we can get a timedelta object with the same in-day time values as the datetime object.

dt2 = datetime.datetime(dt1.year, dt1.month, dt1.day, 0, 0, 0)                    # Creating another datetime
td2 = dt1 - dt2                                                                   # subtraction between two datetime objects
print(td2)                                                                        # printing timedelta
# 8:25:40
