🧠 What Is a Working Days Calculator?

A Working Days Calculator—also called a Business Days Calculator—computes the number of days between two dates, excluding weekends (Sat–Sun) and optionally public holidays, according to your region.

You can also use it in reverse: determine the future date after adding a given number of business days

🔍 How It Works

Select start date and end date (or vice versa).
Decide whether to include the end date.
Choose to exclude weekends only, public holidays only, or both.
Optionally, upload or select holidays for your country
Calculate to get:
- Number of working days
- Date after adding X working days
- Support for custom weekend definitions (e.g., Sun–Thu)

🗓️ Real-World Examples

Project Planning: Determine how many business days are available between April 1 and June 30 (excluding weekends/holidays).
Service SLAs: Count X business days to find due dates—e.g., “deliver within 5 working days” pug.phocassoftware.com+15gigacalculator.com+15omnicalculator.com+15.
HR & Payroll: Calculate leave days or pro-rated work periods excluding weekends and official non-working days calendarlabs.com+2empmonitor.com+2day-off.app+2.

📊 How to Calculate Manually

For a manual estimate:

Count total calendar days between dates.
Compute full weeks × 2 for weekends.
Subtract weekend days.

This works well, but the tool automates for ease and accuracy.
