Paczki Day

Celebrated on 02/17/2026

Quick Fact

Paczki Day, also known as Fat Thursday in Poland, is celebrated on the Thursday before Ash Wednesday. It marks the last chance to indulge in rich, sweet foods before the Lenten fast begins, and bakeries in the US sell over 100 million paczki each year on this day.

Origins and Establishment of Paczki Day

Paczki Day originated in Poland as a pre-Lenten celebration on Fat Thursday (Tłusty Czwartek). The tradition dates back to the Middle Ages, when Christians would use up all the lard, sugar, and eggs in their homes before the Lenten fast, which prohibited such ingredients. The paczki, a deep-fried dough filled with jam or other sweet fillings, became the centerpiece of this feast. Polish immigrants brought the tradition to the United States, particularly in cities like Chicago, Detroit, and Buffalo, where it evolved into Paczki Day, celebrated on Fat Tuesday (Mardi Gras) instead of Fat Thursday to align with the American pre-Lenten calendar.

Evolution and Modern Commemoration

Over time, Paczki Day has shifted from a religious observance to a secular food holiday. In the US, it is now primarily associated with eating paczki on Fat Tuesday, with bakeries offering a wide variety of fillings like prune, raspberry, and custard. The holiday has become a major cultural event in Polish-American communities, featuring parades, paczki-eating contests, and special bakery promotions. In recent years, Paczki Day has gained broader popularity across the US, with non-Polish bakeries and grocery chains joining in the celebration.
