Time Card Calculator

Enter your start, finish and break for each day, and the week adds itself up in hours and minutes and in decimal hours.

Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.

Dates are counted as whole calendar days, so daylight saving changes do not shift the results. When adding months lands on a day the month does not have, such as 31 February, the result is the last day of that month.

How to use it

  1. Choose a tab: Age, Days between, Business days, Add or subtract, Hours or Time card.
  2. Enter the dates. For business days, tick the days you do not work, type any public holidays to skip, and use the second box to add working days to a date.
  3. For times, use Hours to find the time between two clock times, move a clock time forward or back, or add up a list of hours and minutes.
  4. On the Time card, enter each day's start, finish and break. The week's total appears below; add your hourly rate if you want a gross pay figure.
  5. Read the result straight away; press Copy next to any figure you want to keep.

Questions

How do I calculate my hours for the week?

Fill in the in time, out time and break minutes for each day you worked. The total for the week appears below the table in hours and minutes and as a decimal.

Does the time card work for night shifts?

Yes. When the out time is earlier than the in time, the shift is counted as ending the next day.

Does it calculate overtime?

No. It totals hours and can multiply them by a rate you type, but overtime, tax and deductions are not applied.

About this tool

A weekly timesheet in your browser

The time card has a row for every day from Monday to Sunday. For each day it takes the time from clock in to clock out, subtracts the break in minutes, and adds the days together.

  • Night shifts. An out time earlier than the in time is counted as the next morning, so 22:00 to 06:00 is 8 hours before the break.
  • Two totals. The week is shown as hours and minutes, such as 38:30, and as a decimal, 38.50, which is the form most payroll and invoicing systems ask for.
  • Optional pay. Type an hourly rate to multiply it by the decimal hours. Overtime rules, tax and deductions are not applied, because they differ by employer and country.
  • Keep a copy. Copy the summary or download the week as a CSV file for a spreadsheet.

Worth checking

Some employers round clock times to the nearest few minutes, and some pay certain breaks. Fill in the times you were actually paid for and compare the total with your payslip.

Nothing you enter is sent anywhere or saved after you close the page.
