How Timesheet calculator works

Timesheet calculator takes your clock-in and clock-out times for each work period throughout the day, including breaks, and computes your total regular hours, overtime and gross pay. Add multiple rows for a split-shift or a day with several work blocks and it tallies them all.

This is different from the Time duration tool, which measures the gap between two clock times in isolation. The Timesheet is about the full day: accumulating multiple periods, applying overtime thresholds and applying an hourly rate to produce a pay figure. Freelancers, shift workers and consultants use it to cross-check their own records. Set a daily or weekly threshold and hours beyond it are flagged as overtime and multiplied by your configured rate before being added to the total.

Frequently asked questions

Are my worked hours and pay rate sent to Sunasty or stored?

No. All arithmetic, hours totalled, overtime computed, pay calculated, runs in your browser. Your clock-in/out times, hourly rate and any other figures you enter are never transmitted to Sunasty or any third party and are cleared when you close the tab.

How does overtime work?

You set the daily or weekly threshold (commonly 8 hours per day or 40 hours per week). Hours beyond that threshold are flagged as overtime and multiplied by your configured overtime rate (typically 1.5×) before being added to the regular pay total.

How is this different from the Time duration tool?

Time duration answers one narrow question: how many hours and minutes between two clock times? The Timesheet is a full daily ledger: multiple clock-in/out pairs, break deductions, overtime rules and a gross pay calculation, use it for a complete working-day summary.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.
