Since 1929, the University of Helsinki compiled different name day calendars for the Finnish- and Swedish-speaking populations. After 1929, the name day calendar for the Swedish-speaking Finns has been updated nine times: 1950, 1964, 1973, 1989, 1995, 2000, 2005, 2010 and 2015. The updates were mainly done under the same principles as those for the Finnish name day calendar. The main criterion for selecting names for the calendar has been their frequency. Statistics from the Population Register Centre allow for the careful following of name giving amongst the Swedish-speaking Finns.
From the 1980s until 2015, Professor Emerita Marianne Blomqvist was responsible for updating the name day calendar for the Swedish-speaking Finns. Today, the calendar is put out by Leila Mattfolk, PhD.
In essence, the name day almanacs for the Finnish- and Swedish-speaking populations make up a complete set of names that does its best to serve the entire population. If a name cannot be found in the Finnish calendar, it could surely be commemorated on a day found in the Swedo-Finnish calendar – and vice versa.
