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"; "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). Italy In Italy Mardi Gras is called Martedì Grasso (Fat Tuesday). It is the main day of Carnival along with the Thursday before, called Giovedí Grasso (Fat Thursday), which ratifies the start of the celebrations.
