Frequently asked questions
How do I calculate hours worked between two times?
Subtract the start time from the end time. If the shift runs overnight (end earlier than start), add 24 hours. Enter both times above and the calculator handles it, including the decimal-hours figure.
How do I convert minutes to decimal hours?
Divide minutes by 60. So 30 minutes = 0.5 hours, 15 minutes = 0.25 hours, 90 minutes = 1.5 hours. The Minutes ↔ decimal tab converts instantly in both directions.
Does it handle overnight shifts?
Yes. If the end time is earlier than the start time (e.g. 22:00 to 06:00), it's treated as crossing midnight and you get 8 hours.
What are decimal hours used for?
Payroll and billing systems use decimal hours — 7 hours 30 minutes becomes 7.5, which multiplies cleanly by an hourly rate. The calculator shows this figure for every result.
Can I add hours to a time?
Yes — use the Add / subtract tab. Enter a start time and a number of hours (decimals allowed, e.g. 7.5) to get the resulting clock time, wrapping past midnight.
