How this service works
UK working-day calculator using GOV.UK bank holidays for England and Wales, Scotland or Northern Ireland. Next working day, add or subtract working days (e.g. payment settlement, notice periods, delivery dates), count working days between dates, and list bank holidays. Dates must fall within GOV.UK coverage; out-of-range dates are refused, not guessed.
Output
Returns a plain-text summary string indicating the next working day after the supplied date, calculated using official GOV.UK bank holiday data for the specified UK region (England & Wales, Scotland, or Northern Ireland). The summary includes the resolved date in human-readable form.
Example use cases
Payment settlement date calculation
“My customer initiated a bank transfer on 24th December 2025 — what's the next working day it would settle in England and Wales, not counting Christmas Day?”
Notice period start date in Scotland
“An employee handed in their notice today, 1st August 2025, in Scotland — what's the first working day from that date so I can start counting their notice period?”
Delivery date after a bank holiday weekend
“We're dispatching an order on 18th April 2025 in Northern Ireland — what's the next working day after that so I can tell the customer when to expect their delivery?”
Technical details
Endpoint
GEThttps://uk-working-days.agent-fee-check.workers.dev/next?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find the next UK working day after a specific date and must respect official GOV.UK bank holidays for a specific UK jurisdiction (England & Wales, Scotland, or Northern Ireland). Prefer it over generic weekday calculators when UK bank holidays must be accounted for, and over manual lookup when automating payment settlement, notice period, or delivery date logic. It is the right choice when the date must fall within the GOV.UK data coverage window and correctness is more important than guessing.
Side effects
- Date is outside the range covered by the GOV.UK bank holiday data — request is refused with an error, not guessed
- Invalid date format (not YYYY-MM-DD) results in a validation error
- Invalid or unrecognised region enum value returns an error
- Missing required 'date' parameter returns a 400-level error
- Network or upstream GOV.UK data fetch failure may cause a 500-level error
