# A fast, efficient Python library for generating country, province and state
|
|
# specific sets of holidays on the fly. It aims to make determining whether a
|
|
# specific date is a holiday as fast and flexible as possible.

"""Official holidays for Germany in its current form.
|
|
|
|
This class doesn't return any holidays before 1990-10-03.
|
|
|
|
Before that date the current Germany was separated into the "German
|
|
Democratic Republic" and the "Federal Republic of Germany" which both had
|
|
somewhat different holidays. Since this class is called "Germany" it
|
|
doesn't really make sense to include the days from the two former
|
|
countries.
|
|
|
|
Note that Germany doesn't have rules for holidays that happen on a
|
|
Sunday. Those holidays are still holiday days but there is no additional
|
|
day to make up for the "lost" day.
|
|
|
|
Also note that German holidays are partly declared by each province there
|
|
are some weired edge cases:
|
|
|
|
- "Mariä Himmelfahrt" is only a holiday in Bavaria (BY) if your
|
|
municipality is mostly catholic which in term depends on census data.
|
|
Since we don't have this data but most municipalities in Bavaria
|
|
*are* mostly catholic, we count that as holiday for whole Bavaria.
|
|
We added BYP for the municipality in Bavaria with more protestants.
|
|
Here this is excluded.
|
|
- There is an "Augsburger Friedensfest" which only exists in the town
|
|
Augsburg. This is excluded for Bavaria.
|
|
- "Gründonnerstag" (Thursday before easter) is not a holiday but pupils
|
|
don't have to go to school (but only in Baden Württemberg) which is
|
|
solved by adjusting school holidays to include this day. It is
|
|
excluded from our list.
|
|
- "Fronleichnam" is a holiday in certain, explicitly defined
|
|
municipalities in Saxony (SN) and Thuringia (TH). We exclude it from
|
|
both provinces.
