In the United Kingdom, Father's Day is celebrated on the third Sunday of June, same as in the United States and Canada.
In 2023 Father's Day is on June 18th. However, it's worth noting that Father's Day is not a public holiday in the United Kingdom.
Father's Day was first officially celebrated in the United Kingdom in the early 1960s, although there were some precursor celebrations in the early 20th century. The modern holiday of Father's Day in the UK began as a way to honor fathers and celebrate fatherhood, paternal bonds, and the influence of fathers in society, similar to the United States. The concept of Father's Day was introduced in the UK by the American servicemen based in the country and it was popularized by the media and retailers.
