Frequently Asked Questions

How are holidays handled in the calculation?

Holidays are excluded from business days when you provide them in YYYY-MM-DD format. You need to manually add relevant holidays for your region.

Does this account for different time zones?

No, calculations use the local timezone of your browser. For precise cross-timezone calculations, convert dates to a common timezone first.

What if my weekend days are different?

Use the weekend day checkboxes to customize which days count as weekends for your specific situation.
