Summary

About the Hours Calculator

The Hours Calculator is designed for employees, freelancers, and managers who need to quickly tally work hours. Add multiple days, enter start and end times, and optionally subtract break durations to get accurate totals.

How to Use

  1. For each work day, enter the Start Time and End Time using the time pickers.
  2. Enter any Break duration in minutes (e.g., 30 for a 30-minute lunch break).
  3. Click + Add Day to add more days.
  4. Click Calculate Hours to see total hours worked.

How It Works

For each row: Net Hours = (End Time − Start Time) − Break Minutes. If the end time is before the start time, an overnight shift is assumed (24 hours added). All days are summed for the total.

Example

Mon: 9:00 AM – 5:30 PM, 30 min break → 8.0 hours
Tue: 8:30 AM – 4:00 PM, 45 min break → 6.75 hours
Total: 14.75 hours (14 hours 45 minutes)
