Weekly Time Card Calculator

Fill in a full week of clock-in and clock-out times, deduct an unpaid lunch and an optional short break on each day, and the week totals itself — including overtime after your weekly threshold. Entries stay in your browser (no account), and you can print the week straight from the page.

How to use the weekly time card

  1. 1. Pick the week. Choose the Sunday that starts your work week — day names and dates fill in automatically.
  2. 2. Tick the days you worked and enter clock-in and clock-out times. Overnight shifts work the same way: if clock-out is earlier than clock-in, hours run past midnight.
  3. 3. Deduct lunch. The lunch column takes an unpaid break window (a 12:00–1:00 lunch is common). A second short-break column is there for a paid-or-unpaid rest — leave it empty if it does not apply.
  4. 4. Set overtime rules. By default overtime starts after 40 hours in the week. If your workplace pays daily overtime (for example after 8 hours a day), enable the daily option — weekly overtime is then skipped so the same minutes are never counted twice.

Time card with lunch break — how the deduction works

For each day the calculator subtracts the lunch window from the time between clock-in and clock-out. Example: 9:00 AM to 5:30 PM with a 12:00–1:00 PM lunch is 8.5 gross hours minus 1 hour = 7.5 hours worked. Break windows that fall partly outside the shift are clipped to the shift, and overlapping breaks are merged so no minute is deducted twice.

FAQ

Where are my entries saved?

In your browser's local storage on this device. There is no account and nothing is uploaded; clearing your browser data or using another device starts fresh.

Can my employer use this instead of a time clock?

This is a personal adding-up tool, not an official timekeeping system. It is handy for checking your own hours against a payslip, but your employer's records are the ones that count for pay.

Do you have a version for two weeks at a time?

Yes — the biweekly time card calculator shows a full pay period with two weekly overtime windows. For a single shift or a one-off calculation, the hours calculator is quicker.

Estimates only. Totals from this time card are for your own record-keeping. Overtime and break rules vary by employer and location — this tool does not decide whether your hours qualify as overtime, and it is not payroll or legal advice.
