Assumptions and limitations
Only enter active work sessions. Do not also deduct a gap between split sessions as a break.
Clock-time calculations do not account for daylight saving transitions or time-zone changes. This calculator is for estimates and record keeping; it does not establish legal pay or overtime entitlements.
Frequently asked questions
Does this tool store my information on a server?
No. The calculator runs locally in your browser and does not submit your entries to WorkCalc Hub.
Can I use the result for payroll?
Use it as a starting estimate, and verify against official time records, employer rules, and applicable law before processing payroll.
How split shifts add up
Suppose you work 9:00 AM to noon, then 2:00 PM to 6:00 PM. The first session is 3 hours and the second is 4 hours, giving 7 hours of working time. The two-hour gap is not counted because it falls outside both sessions.
What to check before relying on the result
Enter each actual working session separately. Avoid entering overlapping sessions, as overlapping time will otherwise be counted twice. Use unpaid break minutes only for breaks occurring inside the sessions.
To audit the number, calculate each session in minutes first, subtract unpaid minutes, and convert the remainder back to hours and minutes. For decimal hours, divide the net minutes by 60.
