Hours & Minutes Calculator

Hours & Minutes Calculator is the time calculator that handles the math your phone's calculator can't. Add and subtract hours and minutes in H:MM, total a week of work shifts, subtract a lunch break, turn hours into pay, and export a clean timesheet — free, private, and fully offline.

Add and subtract time
Work directly in hours and minutes: 8:15 + 7:45 − 0:30 = 15:30. Chain as many entries as you need, with no cap on the total. Overnight shifts and totals past 24 hours are handled cleanly (23:30 + 2:00 = 25:30), and you get true negative results when you need them (1:00 − 3:00 = −2:00).

Multiply, divide, and convert
Scale a duration by a number (1:30 × 3 = 4:30) or split it (3:00 ÷ 2 = 1:30) — ideal for planning and billing. Switch between H:MM and decimal hours with one tap (1:30 to 1.5), perfect for payroll, invoices, and spreadsheets.

Timesheets and pay
Add up a full week, apply your hourly rate to turn hours into pay, and work out overtime with confidence. Save your calculations to a searchable history you can reuse, then export your history or timesheet to CSV or PDF straight to the share sheet. Copy any result with a single tap.

Built for everyday time math
Contractors and freelancers billing by the hour, shift workers logging overnight hours, consultants tracking billable time, and payroll and HR staff totalling the week all rely on quick, correct time math. Students and anyone adding up hours and minutes will feel at home too.

Free, private, and offline
No ads. No tracking or analytics. No account or sign-in. No in-app purchases and no subscription — every feature is free. Your numbers stay on your device, and no internet connection is required.

A clean, familiar calculator layout means there is nothing to learn. Choose light or dark themes with custom accent colours, and enjoy haptic feedback on every tap.
