It's Going to Be Biblical.
Got me thinking and while I'm good at research I suck at documenting. I was thinking about how mardi gras and lent are right around corner.
Mardi gras has long had connotations with saturnalia, knights of momus, etc.
What caught my eye was the German notation on it.
Germany
The celebration on the same day in Germany knows many different terms, such as Schmutziger Donnerstag or Fetter Donnerstag (Fat Thursday), Unsinniger Donnerstag, Weiberfastnacht, Greesentag and others, and are often only one part of the whole carnival events during one or even two weeks before Ash Wednesday be called Karneval, Fasching, or Fastnacht among others, depending on the region. In standard German, schmutzig means "dirty", but in the Alemannic dialects schmotzig means "lard" (Schmalz), or "fat";[9] "Greasy Thursday", as remaining winter stores of lard and butter used to be consumed at that time, before the fasting began. Fastnacht means "Eve of the Fast", but all three terms cover the whole carnival season. The traditional start of the carnival season is on 11 November at 11:11 am (11/11 11:11).
Epiphany was Jan 6 this year. (Technical start of Mardi gras) culminating on Fat Tuedsay Feb 24.
Lent begins Feb 25 (Ash Wed) ends Easter Sunday. Good Friday falls on 4/10/20 this year.
