Working days vs. calendar days

Working days normally exclude Saturdays and Sundays. When holidays are turned on, selected public holidays are excluded as well.

For work and planning

The calculator is useful for project timelines, office deadlines, HR planning, shipping estimates, payment terms, and administrative reminders.

Choose a region

Select a country and region so the result can account for local public holidays instead of using a generic weekday count.

Did you know?

Many countries use the phrase bank holiday or public holiday, but the practical question is often the same: should that date count as a working day for your deadline?

Review before relying on it

Employers, contracts, industries, and local rules can treat holidays differently, so important deadlines should always be reviewed.

What is included in the working days calculator?
