US Real Due Date Calculator
Calculate when invoices, SLAs, and shipments are really due in the United States. Adjusts for 11 federal holidays plus weekends — so you see the actual business day a payment or deadline falls on, not just the calendar date.
Practical examples
Net 30 invoice adjusted for Labor Day
Invoice dated 2 August with Net 30. Calendar due: 1 September (Monday). If that Monday is Labor Day, the real due date shifts to Tuesday 2 September — the next day banks process ACH transfers.
8 business-hour SLA from Friday afternoon (ET)
Ticket logged at 3:30 PM ET on Friday. With 9 AM-5 PM business hours, only 1.5 hours count Friday. The remaining 6.5 hours resume Monday at 9 AM. SLA deadline: Monday 3:30 PM ET.
5 business-day shipping over Thanksgiving week
Order dispatched Monday before Thanksgiving. 5 business days transit, but Thursday is Thanksgiving (federal holiday) — the carrier skips that day. Delivery arrives the following Monday instead of Friday.
