FAQ

What are decimal hours?

Payroll often needs time in decimal form — e.g. "8 hours 30 minutes" = 8.5 hours. This tool converts automatically.

What if the end time is before the start time (night shift)?

The tool automatically assumes the next day — e.g. 22:00 to 06:00 = 8 hours (crossing midnight).

Can I use this to build a timesheet?

Absolutely — enter daily clock-in/clock-out times to get total worked hours, then use the decimal format for payroll.
