How it’s calculated
We count every weekday in December 2025 and subtract weekends and any UK bank holidays for the selected region. For December 2025 that gives the totals above.
Bank holidays vary by region — Scotland and Northern Ireland have extra holidays that England & Wales does not, and the Summer bank holiday falls on a different Monday in Scotland.
