Work Hours Calculator

How to calculate work hours?

The calculation identifies the total calendar days within your selected date range and filters them to include only the specific working days you have designated. It then applies your specified daily hour duration, subtracting the time allocated for lunch breaks, and finally adjusts for any recognized holidays that fall on working days.

Total Hours = (Working Days × (Daily Hours - (Lunch Minutes / 60))) - (Holiday Days × Daily Hours)

Using the Work Hours calculator: an example

Consider a 2-week period where you work Monday-Friday, 8 hours a day with a 60-minute lunch.

Step-by-step calculation:

1. Identify 10 working days in the 14-day range.
2. Subtract 1 hour lunch from 8 hours to get 7 net hours daily.
3. Multiply 10 days by 7 hours.
4. Result: 70 total working hours.

Frequently Asked Questions

How do I handle partial days?
For specific dates where you work fewer hours, you should either calculate that period separately or adjust the daily hours input to represent the average daily duration across the entire timeframe.

Can I include weekend work?
Yes. The calculator allows you to toggle which days of the week are considered business days. If you work Saturdays or Sundays, simply select them in the working day configuration.

What if my schedule varies significantly?
The calculator is designed for consistent weekly patterns. For varying schedules, we recommend breaking the calculation into multiple segments (e.g., one calculation per week) and summing the results manually.
