Add Days and Hours

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
