“Wetter singen 16 tage” is a German phrase that translates to “weather singing 16 days” in English. It is a traditional practice in some parts of Germany, where farmers and villagers would gather for 16 days to sing and dance to bring about good weather for the upcoming growing season.
The tradition is thought to have originated in the Middle Ages, and it was believed that the singing and dancing would please the weather gods and encourage them to bring rain and sunshine. The 16-day period was chosen because it coincided with the time of year when the crops were most vulnerable to frost and drought.
