Question

How do you calculate the difference between two dates in Python?

Answer 1

To calculate the difference between two dates in Python, you can use the date class from the datetime module. 

Here's an example:

from datetime import date

# Create two date objects
d1 = date(2022, 1, 1)
d2 = date(2023, 3, 28)

# Calculate the difference between the two dates
delta = d2 - d1

# Print the number of days between the two dates
print(delta.days)  # Output: 451
 

In this example, we create two date objects representing January 1, 2022 and March 28, 2023. Then, we calculate the difference between the two dates by subtracting d1 from d2. The result is a timedelta object that represents the difference between the two dates as a duration of time. Finally, we access the days attribute of the timedelta object to get the number of days between the two dates, and we print this value using the print() function.

Answer 2

Use the strptime (date_str , format) function to convert a date string into a date time object as per the corresponding format.

To get the difference between two dates , subtract date2 from date1.

A result is a time delta object.
