Python program to find number of days between two given dates
Given two dates, Write a Python program to find the total number of days between them.
Input : dt1 = 13/12/2018, dt2 = 25/2/2019 Output : 74 days Input : dt1 = 01/01/2004, dt2 = 01/01/2005 Output : 365 days
Naive Approach: One Naive Solution is to start from dt1 and keep counting days till dt2 is reached. This solution requires more than O(1) time.
A Better and Simple solution is to count the total number of days before dt1 from i.e., total days from 00/00/0000 to dt1, then count the total number of days before dt2. Finally, return the difference between the two counts.
Using Python datetime module:
Python comes with an inbuilt datetime module which helps us to solve various datetime related problems. In order to find the difference between two dates we simply input the two dates with date type and subtract them, which in turn provides us the number of days between the two dates.
