Today celebrates the time known as Fat Tuesday, the day where Christians load up on fun before Ash Wednesday. What I find funny about Fat Tuesday is we keep the "fat" part of the tradition, but not so much with the deprivation of Lent.
It's a convenient day to eat beignets even if we have never been to New Orleans. But if we have leftovers tomorrow, we'll eat them then.
Without the religious significance, Fat Tuesday is an excuse to party when there aren't any major holidays nearby.
You can, if you can, still enjoy what Fat Tuesday has to offer. Just remember the significance of why it exists.
