# Python program to find difference between current time and given time

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``) ` ` `  `# This code is contributed by SrujayReddy `

Output:

```2 : 25
3 : 31
Both are same times
```
