<P> Estonians celebrate "Jaaniõhtu" on the eve of the Summer Solstice (June 23) with bonfires . On the islands of Saaremaa and Hiiumaa, old fishing boats may be burned in the large pyres set ablaze . On Jaaniõhtu, Estonians all around the country will gather with their families, or at larger events to celebrate this important day with singing and dancing, as Estonians have done for centuries . The celebrations that accompany Jaaniõhtu carry on usually through the night, they are the largest and most important of the year, and the traditions are almost identical to Finland (read under Finland) and similar to neighbors Latvia and Sweden (read under Sweden). </P> <P> Jaanipäev is usually spent in a summer cottage, where people light bonfires, or at a festival, such as Pühajärve Jaanituli in Otepää . </P> <P> Since 1934, June 23 is also national Victory Day of Estonia and both 23rd and 24th are holidays and flag days . The Estonian flag is not lowered in the night between these two days . </P> <P> On the Faroe Islands, St. John's Eve (jóansøka) is generally not celebrated . However, on the southernmost island of Suðuroy it is observed by lighting a bonfire . Only one bonfire is lit on the island as one of the two biggest towns hosts the celebration alternately every other year . </P>
