During the holiday season in Germany, some popular traditions and customs include decorating Christmas trees, attending Christmas markets, baking and eating traditional treats like stollen and lebkuchen, and celebrating St. Nicholas Day on December 6th. Other customs include Advent calendars, Advent wreaths, and the exchange of gifts on Christmas Eve.
Turkish children do not celebrate Halloween. However, Americans in Turkey have certainly introduced some of the customs there, so the holiday tends to be celebrated by ex-pat Americans, rather than the locals.
To determine if customs is open tomorrow for receiving shipments, you would need to check the specific customs office's schedule, as hours may vary by location and holiday observances. Generally, customs offices are open on weekdays but may close on weekends and federal holidays. It's best to contact the local customs office or check their official website for the most accurate and up-to-date information.
That is such a broad question, I am not sure that could be resonably answered in this way. Each holiday and it's customs has it's own individual origins.
