Finding difference in Timestamps – Python Pandas

Python Server Side Programming Programming

To find the difference in timestamps, we can use index operator i.e. the square brackets to find the difference. For timestamps, we need to also use abs(). At first, import the required library −

import pandas as pd

Create a DataFrame with 3 columns. We have two date columns with timestamp −

dataFrame = pd.DataFrame(
   {
      "Car": ["Audi", "Lexus", "Tesla", "Mercedes", "BMW"],

      "Date_of_Purchase": [
         pd.Timestamp("2021-06-10"),
         pd.Timestamp("2021-07-11"),
         pd.Timestamp("2021-06-25"),
         pd.Timestamp("2021-06-29"),
         pd.Timestamp("2021-03-20"),
      ],
      "Date_of_Service": [
         pd.Timestamp("2021-11-10"),
         pd.Timestamp("2021-12-11"),
         pd.Timestamp("2021-11-25"),
         pd.Timestamp("2021-11-29"),
         pd.Timestamp("2021-08-20"),
      ]
   })

Let us now find the difference between timestamps from both the date columns −

timestamp_diff = abs(dataFrame['Date_of_Purchase']-dataFrame['Date_of_Service'])

Example

Following is the code −

import pandas as pd

# create a dataframe with 3 columns
dataFrame = pd.DataFrame(
   {
      "Car": ["Audi", "Lexus", "Tesla", "Mercedes", "BMW"],

      "Date_of_Purchase": [
         pd.Timestamp("2021-06-10"),
         pd.Timestamp("2021-07-11"),
         pd.Timestamp("2021-06-25"),
         pd.Timestamp("2021-06-29"),
         pd.Timestamp("2021-03-20"),
      ],
      "Date_of_Service": [
         pd.Timestamp("2021-11-10"),
         pd.Timestamp("2021-12-11"),
         pd.Timestamp("2021-11-25"),
         pd.Timestamp("2021-11-29"),
         pd.Timestamp("2021-08-20"),
      ]
   })

print"DataFrame...\n", dataFrame

# find difference in timestamps
timestamp_diff = abs(dataFrame['Date_of_Purchase']-dataFrame['Date_of_Service'])
print"\nDifference between two Timestamps: \n",timestamp_diff

Output

This will produce the following output −

DataFrame...
        Car   Date_of_Purchase   Date_of_Service
0      Audi         2021-06-10        2021-11-10
1     Lexus         2021-07-11        2021-12-11
2     Tesla         2021-06-25        2021-11-25
3  Mercedes         2021-06-29        2021-11-29
4       BMW         2021-03-20        2021-08-20

Difference between two Timestamps:
0   153 days
1   153 days
2   153 days
3   153 days
4   153 days
dtype: timedelta64[ns]
