Working days calculator

자주 묻는 질문

Are public holidays excluded?

Currently we only exclude weekends (Sat/Sun). Public holidays vary by country and region — check your local calendar.

How do I count working days in a month?

Set start = 1st of month, end = last day of month. Most months have 20-23 working days.

Are working weeks always Mon-Fri?

We assume Mon-Fri. Some countries (e.g. parts of the Middle East) have Sun-Thu working weeks — we don't currently support that.

Does it count both endpoints?

Yes — both start and end dates are included in the count if they're working days.

Is the calculator free?

Yes — fully free, no signup, runs in your browser.
