Steps to Calculate Time Difference Between Two Times

1. Convert Times to 24-Hour Format (if necessary):
   • Convert each time to a 24-hour format to simplify calculations.
   • Example:
     • 12:00 PM = 12:00
     • 1:30 PM = 13:30
2. Convert Times to Minutes Since Midnight:
   • Convert each time to the number of minutes past midnight.
   • Formula: Hours * 60 + Minutes
   • Example:
     • 12:00 = 12 * 60 + 0 = 720 minutes
     • 13:30 = 13 * 60 + 30 = 810 minutes
3. Calculate the Difference in Minutes:
   • Subtract the earlier time from the later time to find the difference in minutes.
   • Formula: Later Time in Minutes - Earlier Time in Minutes
   • Example:
     • 810 minutes – 720 minutes = 90 minutes
4. Convert Minutes Back to Hours and Minutes (if needed):
   • Divide the total minutes by 60 to get hours and minutes.
   • Formula: Total Minutes / 60
   • Example:
     • 90 minutes = 1 hour and 30 minutes

Example Calculation

Let’s say you want to find the difference between 8:45 AM and 3:20 PM:

1. Convert to 24-Hour Format:
   • 8:45 AM = 08:45
   • 3:20 PM = 15:20
2. Convert to Minutes Since Midnight:
   • 08:45 = 8 * 60 + 45 = 525 minutes
   • 15:20 = 15 * 60 + 20 = 920 minutes
3. Calculate the Difference:
   • 920 minutes – 525 minutes = 395 minutes
4. Convert Minutes Back to Hours and Minutes:
   • 395 minutes = 6 hours and 35 minutes
