How to Use the Hours Calculator

The hours calculator is designed for anyone who needs to total up work time — from freelancers tracking billable hours to employees filling out weekly timesheets. Here's how to use it:

  • Enter start and end times for each work period using the time fields. Use 24-hour format (e.g., 09:00 and 17:30) or 12-hour format — both are accepted.
  • Add more rows by clicking "+ Add Row" to include additional work periods (e.g., multiple days or separate sessions).
  • Enter break duration in minutes in the break field (optional). This is deducted from the total.
  • Click Calculate to see the total hours and minutes worked, decimal hours (for billing), and a per-entry breakdown.
