Frequently Asked Questions

A working day (or business day) is typically any weekday (Monday through Friday) where official commercial activities, banks, and public institutions operate. Statutory public holidays are deducted from this total.

How are state and province holidays handled?

When you select a country with regional rules (such as the US with all 50 states + DC, Canada, UK, Australia, Germany, or Spain), you can specify your exact state or province to deduct state-specific public holidays.

Can I customize non-standard workweeks (e.g. 4-day or Sun-Thu)?

Yes. Under the Options panel, check or uncheck any combination of the 7 days of the week. For example, selecting Friday and Saturday configures a Middle Eastern work schedule (Sunday–Thursday).
