The last quarter moon will shine like a big, cheesy taco in the sky tonight (May 4), and Taco Bell is celebrating the lunar phase by giving away free tacos. 

For today’s first-ever “Taco Moon” event, the company will give customers a free crunchy taco from 8 p.m. to 11:59 p.m. local time. No purchase is necessary to receive a free taco, and you can order online, via the app or in-person at a participating location.
