Traditional festival days of Wales

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season organized around it.

Easter, also called Pascha or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus Christ, preceded by Lent, a 40-day period of fasting, prayer, and penance.

Saint Patrick was a fifth-century Romano-British Christian missionary and bishop in Ireland. Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, the other patron saints being Brigit of Kildare and Columba. Patrick was never formally canonised, having lived prior to the current laws of the Catholic Church in these matters. Nevertheless, he is venerated as a Saint in the Catholic Church and in the Eastern Orthodox Church, where he is regarded as equal-to-the-apostles and Enlightener of Ireland.

John the Baptist was a Judaean mission preacher active in the area of Jordan River in the early 1st century AD.

Saint David's Day, or the Feast of Saint David, is the feast day of Saint David, the patron saint of Wales, and falls on 1 March, the date of Saint David's death in 589 AD. The feast has been regularly celebrated since the canonisation of David in the 12th century, by Pope Callixtus II, although it is not a public holiday in the UK, with some unofficially celebrating the day.

A patron saint, patroness saint, patron hallow or heavenly protector is a saint who in Catholicism, Anglicanism, or Eastern Orthodoxy is regarded as the heavenly advocate of a nation, place, craft, activity, class, clan, family, or person.

Saint David's Day is currently not a bank holiday in Wales. Some Welsh politicians have proposed that St David's Day, a celebration of Welsh identity, observed on 1 March, be designated as a public holiday. Polls show the proposal to have majority support in Wales. The UK Government holds the power to designate public holidays in Wales, and has refused proposals for either designating the day or devolving powers to the Welsh Government, which supports the proposal. The UK Government stated that designating the day would not be feasible due to the large numbers of commuters crossing the England–Wales border, as well as the economic impact of the proposal. In response to the UK Government's refusal, some public bodies in Wales have unofficially designated the day to be a holiday for their staff. Wales and England have eight public holidays, Scotland has nine, Northern Ireland has ten, whereas the average in Europe is twelve annual holidays.

Calan Mai or Calan Haf is a May Day celebration in Wales held on 1 May. Events start on the evening before, known as May Eve, with bonfires; as with Calan Gaeaf or 1 November, the night before is considered an Ysbrydnos or "spirit night" when spirits are out and about and divination is possible. The tradition of lighting bonfires celebrating this occasion happened annually in South Wales until the middle of the 19th century.

May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on 1 May, around halfway between the spring equinox and summer solstice. Festivities may also be held the night before, known as May Eve. Traditions often include gathering wildflowers and green branches, weaving floral garlands, crowning a May Queen, and setting up a Maypole, May Tree or May Bush, around which people dance. Bonfires are also part of the festival in some regions. Regional varieties and related traditions include Walpurgis Night in central and northern Europe, the Gaelic festival Beltane, the Welsh festival Calan Mai, and May devotions to the Blessed Virgin Mary. It has also been associated with the ancient Roman festival Floralia.

Beltane is the Gaelic May Day festival. Commonly observed on the first of May, the festival falls midway between the spring equinox and summer solstice in the northern hemisphere. The festival name is synonymous with the month marking the start of summer in Ireland, May being Mí na Bealtaine. Historically, it was widely observed throughout Ireland, Scotland, and the Isle of Man. In Irish the name for the festival day is Lá Bealtaine, in Scottish Gaelic Latha Bealltainn, and in Manx Gaelic Laa Boaltinn/Boaldyn. Beltane is one of the principal four Gaelic seasonal festivals—along with Samhain, Imbolc, and Lughnasadh—and is similar to the Welsh Calan Mai.
