Add Days and Hours

Add Days and Hours: Learn

How to add days and hours:

  • Add the days together.
  • Add the hours together.
  • If the number of hours is 24 or more, regroup the hours into days:
    • Subtract 24 from the hours.
    • Add 1 to the days.
    • Repeat until the hours are less than 24.

Example: Add 4 days 21 hours plus 2 days 17 hours:

  • 4 + 2 = 6 days
  • 21 + 17 = 38 hours
  • Since 38 is 24 or more, regroup the hours into days:
    • 38 - 24 = 14 hours
    • 6 + 1 = 7 days
    • Since the hours are now less than 24, we are done.
  • Final answer: 7 days 14 hours
