Others refer to the last three-day period before Ash Wednesday as Mardi Gras. In Mobile, Alabama, social events related to Mardi Gras begin in November, followed by the Mystic Society's festivities on Thanksgiving, then New Year's Eve, followed by parades and balls in January and February, and until midnight the night before.
