There are 12 non-working public holidays, including the Great Union Day, celebrated on 1 December in commemoration of the 1918 union of Transylvania with Romania. Winter holidays include the Christmas and New Year festivities during which various unique folklore dances and games are common: ''plugușorul'', ''sorcova'', ''ursul'', and ''capra''. The traditional Romanian dress that otherwise has largely fallen out of use during the 20th century, is a popular ceremonial vestment worn on these festivities, especially in rural areas. There are sacrifices of live pigs during Christmas and lambs during Easter that has required a special exemption from EU law after 2007. In the Easter, traditions such as painting the eggs are very common. On 1 March features ''mărțișor'' gifting, which is a tradition that females are gifted with a type of talisman that is given for good luck.
