National Tea Day is observed in the United Kingdom every April 21, celebrating the cultural significance of tea in British society. Although tea originated in China, it became popular in Europe largely due to British influence, with the first recorded mention by an Englishman in 1615. The day coincides with Queen Elizabeth II’s birthday and was first celebrated in 2016. Various tea companies, cafes, restaurants, and tea rooms organize events such as tea parties, fairs, and tastings, allowing tea lovers to sample new teas, learn brewing techniques, and enjoy snacks like biscuits and scones. The first tea shop in London, opened by Thomas Twining in 1706, continues to operate and is recognized as a historical site. National Tea Day has become a traditional event for those who appreciate tea culture in the UK.
