If you have a local Raising Cane's, then be sure to join their free rewards Caniac Club in order to get some a free chicken tender on July 27!
Here's the landing page for their National Chicken Finger Day® promo. They love the holiday so much, so they purchased the full trademark status to it in 2019!
They don't explicitly say what the freebies will be this year, but their landing page says “we're giving away 727 prizes to celebrate 7.27” and in previous years they gave away free food, so I expect something similar this weekend.
Update: In addition to the free food, you can now enter their sweepstakes to win additional prizes.
