Do you rep for the House of Ravenclaw? More of a Slytherin supporter? Or are you all in for Hufflepuff or Gryffindor?

The Broadway producers who are bringing the show “Harry Potter and the Cursed Child” back to San Francisco in 2022 are kicking off the Pottermania early with “Wizarding World Wednesdays” at the Safeway Holiday Ice Rink in Union Square.

Each week, fans can show up in their Hogwarts house colors, lace up their skates, take a spin around the ice and enter for a chance to win special “Harry Potter and the Cursed Child” prizes, including opening night tickets for the official Feb. 9 premiere at the Curran Theater.

A different Hogwarts house will be featured at 5:30 and 7 p.m. sessions each Wednesday. On Dec. 15 it will be Ravenclaw, followed by Slytherin on Dec. 22 and Gryffindor on Dec. 29. (Alas, Hufflepuff fans are skating as we write this on Dec. 8.)

Ice rink tickets, which include skate rental, are $19. They must be purchased in advance online at  unionsquareicerink.com.

Previews of the new all-in-one-show “Harry Potter” will begin on Jan. 11, a month before the premiere. Tickets, https://sf.harrypottertheplay.com.
