How it works
Only Saturdays and Sundays are skipped. Public holidays and company closures are not excluded, so check those yourself.
The starting day is not counted. Counting begins with the next day in the chosen direction.
Zero returns the starting date unchanged, even if it is a weekend.
The count must be a whole number from -10,000 to 10,000, and the result must stay in years 0001 to 9999.
Everything runs in your browser. Your input is not uploaded or stored.
