Let's talk about why Thursday is the best day to get tacos this week.
Oct. 4 is National Taco Day, and national and regional taco chains are marking this taco lovers' fiesta, also known as Taco Thursday this year, with free tacos or specials.
According to the made-up food holiday's website, NationalTacoDay.com, last year Americans ate more than 4.5 billion tacos. The site estimates that's 490,000 miles of tacos and 775 million pounds.

Mexican restaurants and taco joints are expected to be busy Thursday. Punchh, a marketing automation platform, found "a giant revenue peak" in taco sales on National Taco Day last year.
Despite the specials, Thursday won't be the biggest day of the year for the Mexican dish, according to an analysis from small business software provider Womply.
"Not surprisingly, the best revenue day of the year for taco shops is Cinco de Mayo," said Brad Plothow, Womply's vice president of brand and communications.
