About these tools

They're made for anyone who fills in a timesheet: logging time against tasks or projects, checking a shift, or turning hours and minutes into the decimal hours that payroll and invoices use. Each page explains how it works, so you can check the sums yourself.

The calculators run entirely in your browser. The work minutes calculator keeps what you type in your browser on your own device so a refresh doesn't lose it, and nothing is sent anywhere.
