Why We Built This

People miscalculate business days for one reason: they forget public holidays. A missed holiday shifts a deadline by a day. That one day can break a contract, delay a payment, or invalidate a court filing. We built WorkingDaysCalc to eliminate that error. Select your country, enter your dates, and the calculator applies the correct holiday rules for you.

Our Data

Public holiday data for all supported countries comes from verified government and official sources. We review holiday calendars before each new year and update them when governments announce changes mid-year. Corrections go live within 30 days of the official announcement. The United States, United Kingdom, Canada, Australia, South Africa, Singapore, Japan, Germany, France, and Brazil are among the 100+ countries covered.

Our Commitment

WorkingDaysCalc is free and will stay free. No registration. No subscription. No data collected from your calculations. No ads blocking your results. We believe a working days calculator should be accessible to a solo contractor and a legal firm managing hundreds of deadlines in equal measure.

How Our Working Days Calculator Handles Public Holidays

Select your country from the dropdown and the correct public holiday calendar loads automatically. The working days calculator skips every nationally recognised public holiday in your selected country alongside weekends.

Working Days Calculator — Supported Countries

Working Days Calculator — How We Keep Data Current

Governments add commemorative holidays, move existing ones, and cancel them.
