March 19

Observed primarily in the Pomeranian region, Kashubian Unity Day commemorates the first documented gathering of Kashubians in 1238. Festivities include folk music, traditional dance performances, and exhibitions showcasing Kashubian costumes and crafts. Local schools and cultural centers organize language workshops to promote the Kashubian tongue and literature. Ceremonial events in local municipalities reinforce community bonds among Kashubian villages. The day fosters pride in Kashubian identity and raises awareness of this distinct Slavic minority's history within Poland.

Alkmund of Derby was a Northumbrian prince who lived in the early 9th century and was killed under mysterious circumstances around 800 AD. He became venerated as a martyr, and his relics were preserved at Derby, attracting pilgrims during the Middle Ages. Local churches occasionally hold special services on March 19 in his honor, recalling his piety and sacrifice. Though less universally known today, Alkmund's legacy remains part of England's early Christian history. Historical accounts and archaeological findings in Derbyshire continue to shed light on his life and cult.
