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.
