Generally christian holidays are pretty important due to a Roman Catholic history,
mainly Christmas and Easter. New Year's Day is a particularly important day as that's
when Czechoslovakia split and thus, is the day the Czech Republic was formed. In
addition Independent Czechoslovak State Day (28th of October) is the day
Czechoslovakia gained independence. An interesting thing as well is that
Christmas is celebrated from the evening of December 24th, all the way through the
26th.
