But do Germans celebrate Halloween? Yes!
Even tough Halloween has no roots in the German culture it is being celebrated nowadays in Germany. The day after Halloween (the First of November) is Allerheiligen (All Saints Day) is a public holiday in Germany in five of the 16 states, namely Baden-Württemberg, Bayern, Rheinland-Pfalz, Nordrhein-Westfalen and Saarland. In these states, post offices, banks, schools will be closed. So, this is a great reason for many Germans to celebrate Halloween.
The first parties and/or attempts to introduce Halloween to the Germans happened in the end of 90’s. It started more like a trend were Clubs and bars were offering Halloween parties/nights especially when the next day is a holiday anyways. Most of the TV stations would show horror movies starting at midnight or a few hours before midnight for those people who like to be save and stay at home.
Many of the candy manufacturers use Halloween as for their marketing strategies . Soon more and more people were into Halloween and enjoyed wearing costumes and consuming candy. Little German kids now go house to house and say the phrase “Süßes, sonst gibt’s Saures” (which translates to “Trick or treat”) to collect their share of candy.
