FAQ
What is the easiest way to find hours between times?
Convert both clock times to minutes, subtract, then divide by 60 for decimal hours.
What if the end time is after midnight?
Use overnight mode. It adds 24 hours to the end time before subtracting the start time.
Can I use this for payroll?
It can help with arithmetic, but payroll rules about breaks, rounding, overtime and local law must be confirmed separately.
