Vulcans, Good Hair Days, and Holidays You Get to Invent: It's a Big Thursday on NBC Palm Springs!

First up, Live Long and Prosper Day! That's right, today marks the birthday of the late Leonard Nimoy, best known for playing the iconic Spock in Star Trek. Whether you can nail the Vulcan hand salute on your own or need a little rubber band assistance, today is the day to celebrate one of sci-fi's most beloved characters.

Can't get enough made-up fun? Today also happens to be National Make Up Your Own Holiday Day, which is exactly what it sounds like. Dealer's choice, people. The world is yours.

And rounding out the trio, it's National Good Hair Day, a day dedicated to confidence, self-care, and a seriously nice-looking coif. Whether your hair is working with you or against you today, own it.
