     doesn't really make sense to include the days from the two former

-    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.
+    "Mariä Himmelfahrt" is only a holiday in Bavaria (BY) and "Fronleichnam"
+    in Saxony (SN) and Thuringia (TH) if municipality is mostly catholic which
+    in term depends on census data. It's listed in "CATHOLIC" category for these provinces.
