Public holidays in Germany
By law, "the Sundays and the public holidays remain protected as days of rest from work and of spiritual elevation" (Art. 139 WRV, part of the German constitution via Art. 140 GG). Thus all Sundays are, in a manner, public holidays – but usually not understood by the term "holiday" (except for, normally, Easter Sunday and Pentecost Sunday). Public holidays apart from the Sundays (there must be some of them constitutionally) can be declared by law by either the Federation or the Länder for their respective jurisdictions. By federal law, only the German Unity Day is made  a holiday at present (Unity Treaty, Art. 2 sect. 2); the others, even the ones celebrated all over Germany, are made holidays by state legislation. List by state. Notes: In addition, the state of Brandenburg has formally declared Easter Sunday and Pentecost Sunday as public holidays. As these are Sundays anyway, they have been left away by the other states, nor counted in the table above (the state of Hesse even declared all Sundays public holidays). Quiet days. A couple of days are designated stille Tage (quiet days) by state legislation, which regularly means that public dancing events, music at  inns (if live or if not much quieter than usual) etc. are prohibited. Some public holidays are quiet days: One de facto public holiday (not determined by law, because it is always on a Sunday, but with officially organized celebrations) is a quiet day: One other Sunday is a quiet day: Some days may be quiet days without being public holidays: In a limited number of cases – apart from All Saints which, however, has long been associated in popular understanding with remembrance of the dead. The status of quiet days is also given to festivities joyous in nature: in Hesse , the highest Christian holidays are half-quiet days (until midday) and in Rhineland-Palatinate, Easter Sunday and Christmas Day are two-thirds-quiet days (until 16 o'clock). For details see the German article on . Flag days. A yet third category that may, sometimes, be called "holidays" in a sense are the "flag days" (Beflaggungstage). Only the very highest institutions, and the military, use the national flags at every day, so the directives when flags "are" to be displayed mark the days in question as special. Flags are to be shown by Federal Decree on and by state decrees on other  days, such as election days for state parliaments, state constitution days, anniversary of the election of the Federal President (in Berlin) and so forth. Frequently flags are ordered "ad hoc" to be shown at half-mast in cases of national mourning. Unofficial holidays. Either Carnival Monday ("Rosenmontag") or Mardi Gras is a de facto holiday in some towns and cities in Catholic western and southern Germany which have a strong Carnival tradition. Also, Christmas-Eve is developing into a sort of semi-holiday: from the middle of the afternoon, it is practically treated as a holiday, and while in the  morning shops are still open, working for other businesses (apart from those that work even on holidays) is becoming more and more unusual; schools are closed in any case. Customs about holidays. Ascension Day (Christi Himmelfahrt) and Corpus Christi (Fronleichnam) are both always on Thursdays. By taking only one day's leave, employees can have a four-day weekend. The Three Kings Day, better known as Epiphany, is 6 January, the day after the 12 days of Christmas. In parts of Germany, it has its own local customs.
