Black Friday is typically the most lucrative day for traffic agents because many shoppers, out-of-towners, and forgetful locals assume it's a parking holiday. In past years, traffic agents have issued about 20,000 tickets on the day after Thanksgiving — netting the city around $900,000. But yesterday marked the Muslim holiday of Id al-Adha, which commemorates the willingness of Ibrahim to sacrifice his son to God, and as such, the city suspended alternate-side-of-the-street parking rules on Black Friday.

According to the Times, the Muslim "Festival of Sacrifice" gave Muslims and non-Muslims cause to celebrate. “On Id day we share the blessings with all New Yorkers,” said Imam Shamsi Ali of the Islamic Cultural Center in Manhattan. “The blessing is that they have the opportunity to have free parking.” Somehow, the New York Post didn't get the memo about Id al-Adha being an officially-recognized city holiday, and reported: "Shoppers in Manhattan were hit with a flurry of parking tickets yesterday — with drivers parking just about anywhere, thinking it was a holiday."
