Enter the order date, the handling time and the transit time in working days. The calculator gives the dispatch day and the delivery day, skipping weekends and the bank holidays of the UK nation you choose, and checks the date against the 30-day limit the Consumer Rights Act 2015 sets when no delivery date was agreed.
Order date and cut-off
Enter the day the order is placed. If it comes in after the seller's or carrier's dispatch cut-off, tick the box: handling then starts on the next working day. An order placed on a day that is not worked, such as a Sunday or a bank holiday, is handled from the first working day after it.
Handling and transit time
Handling time is how long it takes to pick, pack and hand the parcel to the carrier: 0 if it goes the same day. Transit time is what the carrier quotes: 1 for next-day delivery, 2 for a two-day service. Each day counted moves on to the next working day.
Working days and bank holidays
Choose the days on which orders are packed and delivered: Monday to Friday, Monday to Saturday or every day. Bank holidays differ across the UK: Scotland has 2 January and St Andrew's Day but no Easter Monday, and Northern Ireland adds St Patrick's Day and the Battle of the Boyne. If your carrier delivers on bank holidays, choose 'Do not skip bank holidays'.
Use the result
Copy the workings in one click, export them as a CSV file or save them to Priostack. Your recent calculations stay on this device. The bank holiday calendar covers 2026 and 2027; outside those two years, the calculator tells you it only skips the days off in the working week.
Handling starts = the first working day from the order date (from the next day if the order came after the cut-off).
Dispatch = start + handling time, in working days.
Delivery = dispatch + transit time, in working days.
A working day is a day of the chosen working week that is not a bank holiday.
Legal limit if no date was agreed = order date + 30 days.
Example: an order placed on Wednesday 23 December 2026 in England
With 1 working day of handling, the parcel leaves on Thursday 24 December. With 1 working day in transit, Monday to Friday, the calculator skips Christmas Day (Friday 25 December), the weekend and the Boxing Day substitute bank holiday (Monday 28 December), so the parcel arrives on Tuesday 29 December 2026, 6 calendar days after the order. If no delivery date was agreed, the legal limit is Friday 22 January 2027.
