Accordingly, to many Swabian-Allemanic Jesters the date when Fastnacht begins marks a crucial distinctive feature to Karneval. Many people consider January 6 to be the original starting date. However, recent research does not support this opinion. On November 11, quite similar to Fastnachtsdienstag (Shrove Tuesday), starts a pre-Christmas fasting period that lasts for forty days. Hence, on Martinmas, similar traditions to Fastnacht can be ascertained. However, November 11 only evolved into the beginning of Fastnachtssaison (Carnival season) with the emergence of Karneval in the 19th century. After all, a Fastnacht that lasted over Advent season and Christmas would completely have opposed the meaning of these days.
