When is Mardi Gras and When is Ash Wednesday this year?
Well, Good Friday is 3/21, which makes Ressurection Sunday the 23rd. So, I guess you’re looking at 2/12 being Fat Tuesday and the 13th being Ash Wednesday. Which means Mardi Gras is going on... now, maybe?
You may want to check some one else on that—I am not an expert (or even a casual observer) of Roman Catholic holy days or observances. Or on drunken bacchanals held on public streets.
Just speaking personally—Passover, Good Friday, and Ressurection Sunday I pay close attention to.
