# Word of warning:
# ================
# As the holidays are defined on a state level and sometimes even on a district / village level,
# this holiday definition is an approximation of the reality. It should be accurate for most of the cases but
# no guarantee is given that it is correct for all the special cases :-).
# Considers both official holidays and holidays that are handled as if they were official holidays.
#
# Holiday names are in German in case they are celebrated in the German speaking area and in French / Italian otherwise.
#
# Known Issues:
# * ch_ur: 26th of December is not celebrated in case the 25th is a Monday or a Friday.
# * ch_fr: Fronleichnam, Maria Himmelfahrt, Allerheiligen, Maria Empfaengnis is celebrated in all villages except
#         some villages of the district of See.
# * ch_so:  - There are a lot of village holidays not included here.
#           - 1st of May is holiday only starting at noon; not included here.
#           - 19th of March is celebrated only in a couple of villages
# * ch_ar: 26th of December is not celebrated in case the 25th is a Monday or a Friday.
# * ch_ai: - 22nd of September is celebrated only in part of the state.
#          - 26th of December is not celebrated in case the 25th is a Monday or a Friday.
# * ch_ne: 26th of December and 2nd of January are only celebrated in case 25th of December and 1st of January are Sundays
