Know exactly how long you worked.
Enter your start and end times, take out any unpaid break, and see your hours in both clock format and decimal hours for payroll, plus your pay if you add a rate. Overnight shifts are handled automatically.
Your shift
Leave the rate at 0 to just count hours. If your end time is earlier than your start time, the shift is treated as crossing midnight.

Your shift at a glance
Clock time to decimal hours
Payroll systems use decimal hours. Every 15 minutes is a quarter hour: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75.

Pay by shift length
Worked hours and pay at your current rate for common shift lengths (break already removed where it applies).

Work hours, explained
How Work Hours Are Calculated
Work hours are computed by finding the difference between your end time and start time, then subtracting any break periods. The result is expressed in both hours-and-minutes and decimal hours for payroll compatibility.
Decimal Hours for Payroll
Most payroll systems require decimal hours. For example, 8 hours and 15 minutes equals 8.25 decimal hours. This calculator converts automatically so you can enter your timesheet accurately without manual math.
Break Time Requirements
Federal law does not mandate meal or rest breaks, but most states require a 30-minute unpaid meal break for shifts over 5 or 6 hours. Some states also require paid 10-minute rest breaks. Always deduct unpaid breaks from your total hours.
Overtime Considerations
Under the Fair Labor Standards Act, non-exempt employees earn 1.5 times their regular rate for hours over 40 per week. Some states require daily overtime for shifts over 8 hours. Track your daily hours carefully to ensure proper overtime pay.
Common questions
How do I enter times in 24-hour format?
In 24-hour format, hours range from 0 (midnight) to 23 (11 PM). For example, 1 PM is 13, 5:30 PM is hour 17 with 30 minutes, and 9 AM is simply 9.
What if my shift crosses midnight?
If your end hour is smaller than your start hour, the calculator assumes you worked through midnight. For example, start at 22 (10 PM) and end at 6 (6 AM) gives 8 hours.
Are paid breaks included in total hours?
The break time you enter is subtracted from the total. If your break is paid, enter 0 for break minutes to include that time in your total hours worked.
How do I calculate weekly hours?
Calculate each day separately and add the results. If you work the same schedule daily, multiply one day result by the number of days worked.
