March 8 is International Romani Day. According to wikipedia:

“The International Romani Day (April 8) is a day to celebrate Romani culture and raise awareness of the issues facing Romani people. The day was officially declared in 1990 in Serock, Poland, the site of the fourth World Romani Congress of the International Romani Union (IRU), in honour of the first major international meeting of Romani representatives, 7–12 April 1971 in Chelsfield near London.”

It is believed the Romani arrived from Poland in the Lithuanian Grand Duchy, including present-day Belarus, in the late 15th or early 16th century. They are officially recognized as one of Lithuania’s historical ethnic minorities. They were also targeted for extermination as an undesirable ethnic group by the Nazis.
