Free Timesheet Calculator & Online Work Timeline Tracker
Effortless Shift Duration, Unpaid Break Deductions, and Payroll Calculations
Tracking employee attendance, freelance project billing, and daily shift records is fast and error-free with our free timesheet calculator and online timeline calculator. Designed for employees, independent contractors, remote freelancers, and team managers, this tool eliminates the headache of calculating daily work time cards and weekly timesheet summaries manually.
Simply enter your shift start and end times to immediately view your net hours worked. The timeline calculator automatically deducts unpaid lunch breaks and rest periods. It includes dedicated logic for overnight shifts, seamlessly managing work periods that cross the midnight threshold without negative hour calculations. In addition, the engine converts elapsed time into decimal hours (for instance, converting 8 hours and 15 minutes into 8.25 decimal hours), making it effortless to copy directly into corporate payroll, QuickBooks, or client invoices.
Unlike cloud-based attendance software that requires subscription accounts or stores your personal schedule on external databases, this free timesheet calculator operates 100% locally in your web browser. Your salary rates, shift timings, and earnings data remain strictly confidential on your own device.

Work Hours Calculator FAQ
How do I calculate total hours worked using this free timesheet calculator?
Enter your shift start time, end time, and unpaid break minutes. The timeline calculator instantly computes your net working hours, decimal equivalent, and estimated earnings without needing to submit forms or refresh the page.
Can the timeline calculator handle overnight graveyard shifts?
Yes. If your shift begins in the evening (e.g., 9:00 PM) and finishes the following morning (e.g., 5:30 AM), our timeline calculator accurately resolves the midnight crossover.
Why does the timesheet calculator provide decimal hours?
Payroll systems and billing invoices require decimal time (such as 7.75 hours instead of 7 hours 45 minutes) to compute gross pay accurately.
Is my hourly wage and timesheet data kept private?
Yes. All wage calculations run locally in your web browser. No financial data, salary rates, or timesheets are ever uploaded or stored on any server.
