Random Acts of Kindness Day is the name of an unofficial holiday increasingly celebrated around the world by localities or organizations, or nationwide, in order to encourage acts of kindness. The original founder of Random Acts of Kindness Day is unknown.^{[citation needed]}.

The holiday is celebrated annually in the United States on February 17 and in New Zealand on September 1.^[1] In New Zealand, RAK day began at a national level in 2005^[2] by Josh de Jong, Marshall Gray, Megan Singleton and Reuben Gwyn.

A bank holiday is a public holiday in the United Kingdom or a colloquialism for public holiday in Ireland. There is no automatic right to time off on these days, although the majority of the population is granted time off work or extra pay for working on these days, depending on their contract.^[1] The first official bank holidays were the four days named in the Bank Holidays Act 1871, but today the term is colloquially (albeit incorrectly) used for public holidays which are not officially bank holidays, for example Good Friday and Christmas Day.

Prior to 1834, the Bank of England observed about thirty-three saints' days and religious festivals as holidays, but in 1834, this was reduced to just four: 1 May (May Day), 1 November (All Saints Day), Good Friday, and Christmas Day. In 1871, the first legislation relating to bank holidays was passed when Liberal politician and banker Sir John Lubbock introduced the Bank Holidays Act 1871, which specified the days in the table set out below.^[2] The English people were so thankful that they called the first Bank Holidays St Lubbock's Days for a while.^[3] Scotland was treated separately because of its separate traditions; for example, New Year is a more important holiday there.^{[citation needed]}
