Time Calculator — Add, Subtract & Duration (समय क्याल्कुलेटर)

A free time calculator for the three time-maths jobs people actually need: add or subtract two durations (like 2 h 30 m + 1 h 45 m), find the duration between two clock times (handy for work hours and shift length, including overnight shifts), and add or subtract hours and minutes to a time of day (e.g. what time is it 3 hours 15 minutes after 10:00). Every result also appears as total minutes and decimal hours, which is exactly what timesheets and payroll need.

It works in hours, minutes and seconds, handles times that cross midnight, and updates the moment you type. Everything runs in your browser — nothing you enter is uploaded or stored anywhere.

How to use this time calculator

1. Pick a mode — जोड / घटाउ (add/subtract two durations), दुई समयबीच (duration between two times) or समयमा थप्नुहोस् (add/subtract time to a clock time).
2. Enter the hours, minutes and seconds — or the clock times — in the fields shown.
3. Use the + / − buttons to choose whether to add or subtract, and tick overnight when a shift crosses midnight.
4. The result, total minutes and decimal hours appear instantly and update as you type.

Decimal hours are useful for pay: 8 h 30 m = 8.5 hours, so at an hourly rate you just multiply by 8.5.

Frequently Asked Questions (FAQ)

How do I add hours and minutes together?

Use the जोड / घटाउ mode, enter each duration as hours, minutes and seconds, keep the + button selected, and the calculator adds them — e.g. 2 h 30 m + 1 h 45 m = 4 h 15 m. Minutes over 60 roll into hours automatically.

How do I calculate hours worked between two times?

Switch to दुई समयबीच, set the start time (e.g. 09:00) and end time (e.g. 17:30), and you get 8 h 30 m — also shown as 510 minutes and 8.50 decimal hours for payroll.

How does it handle an overnight or night shift?

Tick the overnight (cross-midnight) box. The end time is then treated as the next day, so 22:00 → 06:00 correctly returns 8 hours instead of a negative number.

What are decimal hours?

Decimal hours express minutes as a fraction of an hour: 30 minutes = 0.5, 15 minutes = 0.25. So 8 h 30 m = 8.5 hours. It makes wage calculations easy — multiply the decimal hours by the hourly rate.

Is my data stored anywhere?

No. The whole calculation happens in your browser. Nothing you type is sent to or saved on any server.
