An hours calculator finds elapsed time between two clock times or two date-time stamps—including overnight same-day spans and multi-day ranges—and shows the result in hours, minutes, and decimal hours.
Enter a start time and end time to see how many hours and minutes passed between them. The same-day calculator rolls past midnight when the end clock is earlier than the start (for example 10:00 PM to 6:00 AM counts as 8 hours). The date calculator adds calendar days when your range spans more than one day.
Use it for shift length checks, appointment gaps, project logs, or travel planning. It measures elapsed clock time only—it does not subtract breaks or compute payroll totals (use Work Hours Calculator or Hours Calculator with Break for net paid time).
