St John's Day and the second day of the Midsummer celebrations (although this is not the astronomical summer solstice, see June 20) (Roman Catholic Church, Europe), and its related observances: Sânziene (western Carpathian Mountains of Romania)

Sânziană is the Romanian name for gentle fairies who play an important part in local folklore, also used to designate the Galium verum or Cruciata laevipes flowers. Under the plural form Sânziene, the word designates an annual festival in the fairies' honor. Etymologically, the name comes from the Latin Sancta Diana, the Roman goddess of the hunt and moon, also celebrated in Roman Dacia. Diana was known to be the virgin goddess and looked after virgins and women. She was one of the three maiden goddesses, Diana, Minerva and Vesta, who swore never to marry.

The Carpathian Mountains or Carpathians are a range of mountains forming an arc across Central Europe and Southeast Europe. Roughly 1,500 km (930 mi) long, it is the third-longest European mountain range after the Urals at 2,500 km (1,600 mi) and the Scandinavian Mountains at 1,700 km (1,100 mi). The highest peaks in the Carpathians are in the Tatra Mountains, exceeding 2,600 m (8,500 ft), closely followed by those in the Southern Carpathians in Romania, exceeding 2,550 m (8,370 ft).

Romania is a country located at the crossroads of Central, Eastern and Southeast Europe.

Romania is the twelfth-largest country in Europe and the sixth-most populous member state of the European Union. Europe's second-longest river, the Danube, empties into the Danube Delta in the southeast of the country. The Carpathian Mountains cross Romania from the north to the southwest and include Moldoveanu Peak, at an altitude of 2,544 m (8,346 ft).
