Hromnice is know in the English-speaking countries as the Groundhog Day, religiously also as Candlemas. It is celebrated on February 2.
The Czech name Hromnice refers to a special type of candles called hromničky. It used to be a celebration of the upcoming spring and the aim of the festivities was to secure protection from fire, storm and thunder (thunder – hrom). One of the customs was the consecration of the aforementioned candles which were placed on the window during the storms to protect the household from the element which caused a lot of damage and death.
It is not without interest that the church also calls this holiday “Presentation of Jesus at the Temple”.
