# Get time difference in seconds and minutes with Python

In today’s tutorial we will learn how to use how to calculate time differences in Python and Pandas.

### Find the difference between timestamps in seconds

We will start by defining our datetime time stamps. We then define a timedelta. The timedelta is by default expressed in days and hours. Therefore, we then use the total_seconds() method to calculate the difference in seconds.

``````import datetime

#define the timestamps
start_time = datetime.datetime(2022,8,19,15,30,0)
end_time = datetime.datetime(2022,8,25,20,30,0)

#define a timedelta object
elapsed_time = end_time - start_time

#calculate the difference in seconds
time_seconds = (elapsed_time).total_seconds()

print('The elapsed time is: ' + str(time_seconds) +' seconds')``````

The result will be:

`The elapsed time is: 536400.0 seconds`

Important: Before working with the datetime module, make sure that you have imported it into your Python program. Otherwise you will receive the following name error:

`NameError: name 'datetime' is not defined`

### Calculate the time difference in minutes and hours

In a similar fashion we can perform additional tweaks to find the time in minutes.

``````time_minutes = (end_time - start_time).total_seconds()/60

print('The elapsed time is: ' + str(time_minutes) +' minutes')``````

This will return:

`The elapsed time is: 8940.0 minutes`

And for hours:

``````time_hours = (end_time - start_time).total_seconds()/3600

print('The elapsed time is: ' + str(time_hours) +' hours')``````

Will return:

`The elapsed time is: 149.0 hours`

### Calculate time differences with Pandas

In Pandas the time calculation work quite similarly. Below is a trivial example, typically your data will be organized in columns containing timestamps. Still, the mechanics are similar.

``````import pandas

# creating timestamps
start_time_pd = pd.to_datetime(start_time)
end_time_pd = pd.to_datetime(end_time)

#calculating the timedelta and returning the delta in seconds

delta_pd = (end_time_pd-start_time_pd)
time_seconds = delta_pd.total_seconds()

print('The elapsed time is: ' + str(time_seconds) +' seconds')
``````
