Frequently Asked Questions
How do I add hours and minutes together?
Convert all values to minutes, sum them, then convert back. Example: 1h 45m + 2h 30m = 105 + 150 = 255 minutes = 4h 15m.
What if my duration spans midnight?
Add 24 hours to the end time before subtracting the start time. Example: Start 10 PM, end 6 AM → 6 AM + 24h = 30:00 − 22:00 = 8 hours.
