Frequently Asked Questions

What counts as a business day?

Business days are the weekdays you keep enabled (typically Monday–Friday). Weekends are excluded, and optional holidays can be excluded too.

How do I include or exclude the start/end date?

Use the “Include start date” and “Include end date” toggles to control whether those days are counted.

How do I add holidays?

Enter one holiday date per line in YYYY-MM-DD format. Those dates will be excluded when holidays are enabled.

Can I change which weekend days are excluded?

Yes. Toggle Saturday and Sunday to match your work schedule or locale.

Does this consider time of day?

No. It works with calendar dates only, which helps keep results consistent.
