In case, you were wondering, Saints Cyril & Methodius Day commemorates the establishment of the Slavic Glagolitic and Cyrillic alphabets by the brother-Saints Cyril and Methodius. Even if there is evidence of the Cyrillic alphabet not being created by Cyril and Methodius at all but by their scholar, Clement of Ohrid, the alphabet still bears Cyril's name since there is not strong enough a proof that denies Cyril and Methodius’ authorship.
The other holidays seem quite self-explicable, except for maybe Jan Hus Day which commemorates religious reformer Jan Hus who was, as a consequence of his endeavors, burned at the stake on July 6, 1415.
