Work Hours Calculator
Direct calculation of elapsed worked time from clock-in, clock-out, and break inputs for single shifts or multiple daily intervals.
Shift Clock In & Out Times
Calculate elapsed time and subtract unpaid breaks.
Step-by-Step Instructions
- 1Enter your shift start time and finish time in 24-hour or AM/PM format.
- 2Enter any unpaid break minutes taken during the shift (e.g. 30 minutes).
- 3Toggle multiple work intervals if you split your day into morning and afternoon shifts.
- 4View instant breakdown of gross elapsed time, net worked time, and decimal hours.
Elapsed Time Calculation Formula
Elapsed shift time is determined by converting start and end timestamps into minutes from midnight. When the end time is numerically lower than the start time, 1,440 minutes (24 hours) are added to account for crossing midnight.
Gross Elapsed Minutes = (End < Start) ? (1440 - Start + End) : (End - Start)How to Calculate Hours Worked from Start and End Times
Understanding the Mathematical Step-by-Step Method
Calculating working hours requires three clear steps: convert timestamps into continuous minutes from midnight, calculate the elapsed difference between end and start times, and subtract non-working break periods.
For example, working from 09:15 to 17:45 represents 8 hours and 30 minutes of total elapsed time (510 minutes). Deducting a 30-minute lunch leaves 480 working minutes, exactly 8.00 decimal hours.
Split Shifts and Multiple Daily Intervals
Calculating Morning and Evening Shifts on the Same Day
Many service, transportation, and healthcare workers work split shifts (e.g., morning route from 06:30 to 10:00, followed by an afternoon route from 14:00 to 18:30).
Our tool allows you to add multiple shift intervals to combine separate blocks into a consolidated daily total with independent break subtractions.
Clock in at 08:00, clock out at 16:45 with a 45-minute lunch break.
- •Start: 08:00 (480 mins from midnight). End: 16:45 (1,005 mins from midnight).
- •Gross elapsed time: 1,005 - 480 = 525 minutes (8h 45m).
- •Subtract unpaid break: 525 - 45 = 480 minutes.
- •Convert to decimal: 480 ÷ 60 = 8.00 decimal hours.
Frequent Calculation Mistakes
- ✕Confusing elapsed span with net worked hours by forgetting break deductions.
- ✕Assuming 8.3 hours means 8 hours and 30 minutes (it is actually 8 hours and 18 minutes).
Questions & Answers
How do I calculate hours worked if I work past midnight?
If your shift starts at 22:00 (10 PM) and finishes at 06:00 (6 AM), the calculator automatically detects that the finish time is on the next day and adds 24 hours (1,440 minutes), yielding 8 hours elapsed time.
Can I calculate multiple shift intervals in one day?
Yes. Use the split shift option to enter morning and afternoon intervals separately, deducting unpaid intervals between them.
