How does the hours calculator handle overnight shifts that cross midnight?

When your end time is earlier than your start time (e.g., 10:00 PM to 6:00 AM), the calculator automatically detects that the shift ends on the following day and adds 24 hours, giving you the correct elapsed duration without requiring manual date inputs.

How are decimal hours converted from hours and minutes?

Decimal hours equal the whole hours plus minutes divided by 60. For instance, 8 hours and 30 minutes equals 8 + (30 / 60) = 8.50 decimal hours. Payroll systems and billing software universally rely on decimal hours for timesheet computations.

How does unpaid break deduction work?

You can deduct lunch or rest breaks using preconfigured buttons (15m, 30m, 45m, 60m) or enter a custom minute amount. The calculator subtracts break minutes from gross shift duration to report accurate net billable hours.

Are my work hours, wage rates, or schedule data stored on any server?

No. All computations execute 100% locally in your device's browser memory. Zero timestamps, work hours, or wage amounts are ever uploaded or transmitted across the network.

15 Minutes	0.25 Hours	1/4 Hour	8 to 22 minutes rounds to 15m (0.25h)
30 Minutes	0.50 Hours	1/2 Hour	23 to 37 minutes rounds to 30m (0.50h)
45 Minutes	0.75 Hours	3/4 Hour	38 to 52 minutes rounds to 45m (0.75h)
60 Minutes	1.00 Hours	1 Full Hour	53 to 67 minutes rounds to 60m (1.00h)

Frequently Asked Questions

If your end time is chronologically earlier than your start time (such as 10:00 PM to 6:00 AM), the calculator automatically detects that the shift concluded on the subsequent morning and rolls over 24 hours, presenting the correct total shift length.

Decimal hours equal hours plus minutes divided by 60. For example, 7 hours and 45 minutes equals 7 + (45 / 60) = 7.75 decimal hours. Payroll, accounting, and billing systems multiply decimal hours by hourly wage rates.

Unpaid breaks are subtracted directly from gross shift duration to report net working hours. For example, a shift from 8:30 AM to 5:00 PM (8.5 gross hours) with a 30-minute lunch deduction yields exactly 8.00 net billable hours.

Never. Every calculation executes 100% locally in your device's browser memory using native Web APIs. Zero dates, hours, pay rates, or confidential timesheets ever leave your device.
