How it works

2

For Between mode, enter the end date; for Add/Subtract mode, enter the workday count.

3

Choose a weekend pattern and optionally add holiday dates, then calculate.

Important notes

Public holidays differ by country, state, employer and school. Calquent therefore lets you enter extra non-working dates instead of assuming a universal holiday calendar.
