+# The source for Czech data is: Kdy začíná a končí letní čas.
# https://kalendar.beda.cz/kdy-zacina-a-konci-letni-cas
+# Its main text disagrees with its quoted sources only in 1918,
+# where the main text says spring and autumn transitions
+# occurred at 02:00 and 03:00 respectively (as usual),
+# whereas the 1918 source "Oznámení o zavedení letního času v roce 1918"
+# says transitions were at 01:00 and 02:00 respectively.
+# As the 1918 source appears to be a humorous piece, and it is
+# unlikely that Prague would have disagreed with its neighbors by an hour,
+# go with the main text for now.

# We know of no English-language name for historical Czech winter time;
# abbreviate it as "GMT", as it happened to be GMT.
