UK Business Day Calculator
Calculate business days in the United Kingdom with England and Wales bank holidays pre-selected. This calculator excludes all UK bank holidays including Good Friday, Easter Monday, the May Bank Holidays, Boxing Day, and Christmas Day. Use it for contract timelines, HMRC deadlines, employee notice periods, and any business obligation governed by UK working day conventions.
How UK Business Days Are Defined
In the United Kingdom, business days are Monday through Friday, excluding bank holidays in England and Wales (which differ from those in Scotland and Northern Ireland). The calculator uses England and Wales bank holidays, published annually by the UK government. Most UK commercial contracts, employment agreements, and financial regulations use “business days” to mean days on which banks are open in England, which aligns with this calculator's default.
UK Bank Holidays (England and Wales)
Standard UK bank holidays include:
- New Year's Day (January 1)
- Good Friday
- Easter Monday
- Early May Bank Holiday (1st Monday in May)
- Spring Bank Holiday (last Monday in May)
- Summer Bank Holiday (last Monday in August)
- Christmas Day (December 25)
- Boxing Day (December 26)
The exact dates for moveable holidays vary by year. Scotland and Northern Ireland have different bank holiday schedules not covered by this calculator. How we determine holidays →
Common Use Cases in the UK
UK payment terms legislation, particularly the Late Payment of Commercial Debts (Interest) Act 1998, uses calendar days for statutory payment periods (typically 30 days from invoice). However, many UK commercial contracts specify business days. Employment law notice periods are generally counted in calendar days. UK financial services firms regulated by the FCA must respond to complaints within specific business day windows.
