Mother's Day in Slovenia is celebrated every March 25. It is a family holiday that follows the American tradition initiated by Anna Jarvis, which gained popularity in Europe during World War I when American soldiers sent postcards to their mothers. Slovenia adopted this holiday in 1991, following its independence from the former Yugoslavia. On this day, various activities are organized in kindergartens and primary schools, where children learn about the significance of Mother's Day. Additionally, Slovenia addresses birth rates through social programs aimed at encouraging childbirth among young women, with modern Slovenian women typically having their first child at the age of 30, compared to 25 years ago when it was around 25.
