UK Real Due Date Calculator
Calculate when invoices, SLAs, and shipments are really due in the United Kingdom. Adjusts for all 8 England and Wales bank holidays plus weekends — so you see the actual business day a payment or deadline lands on, not just the calendar date.
Practical examples
Net 30 invoice adjusted for Easter bank holidays
Invoice dated 1 March with Net 30. Calendar due: 31 March. If Good Friday is 28 March, Easter Monday 31 March — the real due date shifts to Tuesday 1 April.
8 business-hour SLA from Friday afternoon
Support ticket logged at 4 PM on Friday with 9 AM-5:30 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.
5 business-day delivery after daily cut-off
Order placed at 5 PM (after 4 PM cut-off). Dispatch begins the next working day. 5 UK business days transit, skipping the late May bank holiday — delivery arrives one day later than expected.
