How UK working days are counted
Working days comprise standard business days (Monday to Friday). Saturdays and Sundays are excluded from the working total.
Statutory UK bank holidays are deducted automatically based on the selected jurisdiction (England and Wales, Scotland or Northern Ireland), as bank holiday calendars differ between devolved nations.
