Python program to find difference between current time and given time
  • Last Updated : 30 Jan, 2020

Given two times h1:m1 and h2:m2 denoting hours and minutes in 24 hours clock format. The current clock time is given by h1:m1. The task is to calculate the difference between two times in minutes and print the difference between two times in h:m format.

Examples:

Input : h1=7, m1=20, h2=9, m2=45
Output : 2 : 25
The current time is 7 : 20 and given time is 9 : 45.
The difference between them is 145 minutes.
The result is 2 : 25 after converting to h : m format.

Input : h1=15, m1=23, h2=18, m2=54
Output : 3 : 31
The current time is 15 : 23 and given time is 18 : 54.
The difference between them is 211 minutes.
The result is 3 : 31 after converting to h : m format.

Input : h1=16, m1=20, h2=16, m2=20
Output : Both times are same
The current time is 16 : 20 and given time is also 16 : 20.
The difference between them is 0 minutes.
As the difference is 0, we are printing “Both are same times”.



Approach:

  • convert both the times into minutes
  • find the difference in minutes
  • if difference is 0, print “Both are same times”
  • else convert difference into h : m format and print

Below is the implementation.




# Python program to find the
# difference between two times
  
  
# function to obtain the time
# in minutes form
def difference(h1, m1, h2, m2):
      
    # convert h1 : m1 into
    # minutes
    t1 = h1 * 60 + m1
      
    # convert h2 : m2 into
    # minutes 
    t2 = h2 * 60 + m2
      
    if (t1 == t2): 
        print("Both are same times")
        return 
    else:
          
        # calculating the difference
        diff = t2-t1
          
    # calculating hours from
    # difference
    h = (int(diff / 60)) % 24
      
    # calculating minutes from 
    # difference
    m = diff % 60
  
    print(h, ":", m)
  
# Driver's code
if __name__ == "__main__":
      
    difference(7, 20, 9, 45)
    difference(15, 23, 18, 54)
    difference(16, 20, 16, 20)

Output:

2 : 25
3 : 31
Both are same times
