The Empire State Building will be illuminated green this weekend to mark the Islamic holy days of Eid-al-Fitr (EED-ALL-FEET-er).
The joyous "Festival of Fast-breaking" marks the end of Ramadan, a month of intense spiritual renewal.
This year is the first time the famous skyscraper will be aglow for the Islamic holiday. A spokeswoman for the building's owner says it will be an annual event, in the same tradition of the yearly skyscraper lighting for Christmas and Hanukah.
In Islam, the color green symbolizes a happy occasion and the importance of nature. It will be illuminated from Friday through Sunday.
