Bank holidays are public holidays where the majority of the working population in the UK have a day off work.
It originates from the Church's calendar of saints' days and religious festivals with many existing bank holidays retaining some link to Christian holy days or feast days.
Aside from the obvious Christmas Day, Good Friday and Easter Monday, the spring bank holiday was originally Whit Day, linked to Pentecost when the Holy Spirit was given to the disciples.

Although there is no automatic right to time off on bank holidays, most people are granted a day off or extra pay for working on these days.
Here are the remaining bank holiday dates for England and Wales in 2017:
Good Friday: 14 April
