One of the most celebrated days associated with workers group is St. Barbara's Day on December 4th. St. Barbara is a patron of coal miners.
Miners are dressed in the special uniforms during Barbórka. The uniform consists of black suit and hat with a feather. The color of the feather (white, red or black) depends on the rank of the miner. Miners wear their decorative uniforms not only during Barborka but also for weddings, funerals and other important political or social ceremonies. Below is a picture of miners in their decorative uniforms with red feathers.
