Example
- 09:00 to 17:30 → 8 hours (510 minutes, 8.50 decimal hours)
- 09:15 to 17:45 → 8 hours 30 minutes (8.50 h)
Formula
Both times convert to minutes past midnight; a negative result means the interval crosses midnight, so 1440 minutes is added. Decimal hours are useful for timesheets and payroll, which usually bill in tenths or hundredths of an hour.
