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]
