FAQ

## About this calculator

**Does it skip holidays?**

No. Business days here skip weekends only.

**How do I count backward?**

Enter a negative number of days.

**Can I rely on it for a legal deadline?**

Check the rule that sets the deadline, since some count differently or roll a weekend deadline to the next business day. This is general information, not legal advice.

**How do business days differ from calendar days?**

Calendar days count every day, including weekends. Business days here count Monday through Friday and skip Saturday and Sunday.

**What if a deadline lands on a weekend?**

Some rules move it to the next business day and others do not. Check the rule or agreement that sets your deadline.

**Is anything saved?**

No. The math runs in your browser and nothing you enter is sent to us.
