Quick answer
Bank holidays can move a deadline when the wording says business days or working days. They usually do not change a pure calendar-day count.
The simple rule
If the deadline is in calendar days, bank holidays usually still count. If the deadline is in business days or working days, public holidays are often excluded.
Examples
A five-business-day deadline over Easter may land later than expected. A payment promise over Christmas and New Year may also be pushed out if public holidays are excluded.
When bank holidays matter most
Bank holidays are most likely to affect payment promises, delivery windows, complaint deadlines, support SLAs, and formal response dates that use working-day wording.
