Understanding Hours Calculation

Calculating work hours accurately is essential for payroll, scheduling, and project management. This tool allows you to log multiple shifts, account for daily breaks, and automatically handle overnight work durations.

Smart Shift Detection

Automatically calculates overnight shifts and complex break schedules to ensure every minute is accounted for accurately.

Work Duration Formula

Net Hours = (End Time - Start Time) - Break Time

Duration is calculated as the total elapsed time between start and end. If end time is before start time, we assume an overnight shift (+24 hours). Breaks are deducted from the gross duration.

Common Scenarios

Standard 8-Hour Shift

Working 09:00 to 17:00 with a 30-minute break equals 7.50 work hours.

Overnight Shift

Working 22:00 to 06:00 with no break correctly calculates as 8.00 work hours.
