Mother's Day is a festival which draws attention to motherhood joys and celebrate the memory of one's mother, but is also a commercial festival, which in Sweden occurs on the last Sunday in May. The day is an official flag day in Finland, but other than a general flag day in Sweden, but flags are common.
The day was introduced in Philadelphia in 1908 by the American Ann Jarvis to the anniversary of her own mother, Anna Jarvis, death to honor its memory. On May 10, 1908 was therefore a religious service with a focus on the fourth commandment and mother love. The church was decorated by Jarvis himself and to all the visitors were white carnations out, the mother's favorite flower.
The day was spread in the rest of the United States in the years 1914 and became a legal holiday. Although the custom came to Europe, first to Britain and then to Scandinavia. In Sweden, Mother's Day was celebrated for the first time in 1919 at the initiative of Cecilia Bååth-Holmberg.
However, it was many decades later as the day drew attention to a greater extent. People born in the early twentieth century and their children celebrated the days not to any great extent. Many believe that had only days to come, for commercial reasons to merchants would sell more.
They thought the same thing about Father's Day which was celebrated not on any significant degree the first decades. Only recently have these days will be dealt with more extensively in Sweden.
In The Encyclopædia Britannica says: "A festival derived from mother worship in ancient Greece. Downright mother worship with ceremonies to Cybele or Rhea, the mother great gods, exerted March 15 around Asia Minor." - (1959), Volume 15, page. 849th
Mother's Day is celebrated in most Western countries, but on different dates: In Spain, Mother's Day the first Sunday in May. in the U.S., Denmark, Germany and Finland the second Sunday in May, in the UK and Ireland fourth Sunday of Lent (ie three weeks before Easter), in Norway the second Sunday in February, in Sweden last Sunday in May.
In Argentina, the third Sunday in October. The fact that Sweden is celebrating two weeks later than the U.S. is probably because the spring is longer now and the chance to pick fresh flowers are larger.
