Well, shame they got the day wrong...
Very observant Lenka, however......
In Poland, pączki are eaten especially on Fat Thursday (Tłusty Czwartek), the last Thursday prior to Ash Wednesday and the beginning of Lent.
In North America, particularly the large Polish communities of Chicago, Detroit, Milwaukee, and other large cities across the Midwest and Northeast, Paczki Day is celebrated annually by immigrants and locals alike.
The date of this observance merges with that of pre-Lenten traditions of other immigrants on Fat Tuesday.
With its sizable Polish population, Chicago celebrates the festival on both Fat Thursday and Fat Tuesday.
