Work Day Hour Calculator

Enter your clock-in time and clock-out time for the day, and the calculator automatically computes your total hours worked. It handles time format conversions and provides accurate daily hour calculations.

Yes, enter your break durations and the calculator automatically subtracts break time from your total hours. This gives you accurate paid hours for the day, accounting for lunch breaks and other time off.

Enter your start time and end time, and the calculator automatically handles overnight shifts that cross midnight. It correctly calculates the duration even when your shift spans two calendar days.

Yes, you can enter hours for multiple days and the calculator totals them. It shows daily breakdowns and weekly totals, making it easy to track hours across a work period.

The calculator supports both 12-hour (AM/PM) and 24-hour time formats. It automatically recognizes the format you use and performs accurate hour calculations.

Create one or more shifts by entering start and end times for each work period, such as 09:00–17:00 or an overnight span. The calculator converts each shift to minutes, handles cases where the end time passes midnight, and sums everything into a single total of worked hours and minutes.

This tool focuses on shift-based daily time rather than calendar ranges, so you represent only the actual work periods you plan to pay or track. To exclude non-working days, simply omit shifts for weekends and holidays; the calculator only counts the hours you explicitly enter as shifts.

Break the range into the specific shifts actually worked on each business day (for example 09:00–17:00 Monday through Friday) and add them as separate entries. The engine then aggregates all those intervals into gross minutes, applies any configured automatic break deductions, and reports the net business hours worked.

Enter each custom period as a shift row, adjusting start and end times to match your real working patterns, including split days or night shifts. Policy settings like Standard, California, or Freelancer determine how the total minutes are split into regular, overtime, and double-time buckets, all based purely on the time ranges you supply.

The summary card always keeps everything in minutes internally and formats the results as hours and minutes, so partial hours are never lost. You can read both the human-friendly \"Xh Ym\" display and the underlying minute totals for regular, overtime, double-time, and break deductions in the detailed log.
