It’s not even Thanksgiving, but the December holiday season has (unofficial) arrived. If you’re itching to get into the spirit, head to one of the seasonal shows (Wintuk, White Christmas and the Radio City Christmas Spectacular all started this week), or click through our holiday section to see all the fun that lies ahead. Not quite ready to embrace Santa and his merry elves? There’s plenty of great events happening this weekend, most of which are completely free—which means less spending, and thus more gift-giving next month.

Stop by the Brooklyn Public Library for a party to kick off the commemorative Sesame Street 40th Anniversary exhibit; a costumed Elmo will even greet little ones. If you find yourself on the Upper West Side on Saturday, pop into the JCC’s open house, or take a listen to the Demolition String Band in Tribeca on Sunday. Looking for something a little more literary? Peek into the pop-up book party at Books of Wonder on Saturday, where authors will read from their 3-D tomes. Peruse all of our no-cost picks here.

Looking for other options on Saturday? Check out the Yankee Fair in Brooklyn Heights, where Hicks and Henry Streets will be transformed into a giant fairground, or take in some live music with Father Goose at the Fillmore. See all Saturday events here.

There’s plenty to do on Sunday, too. Three kindie concerts get little booties shakin’ around town: Catch Gustafer Yellowgold at the Jewish Museum, Ratboy Jr. at Bowery Poetry Club and the Kidrockers at The Living Room. Get your giggle on at Cirkus Cirkor, where performers mesmerize with their jaw-dropping stunts. Browse all Sunday picks here.
