What are the popular May holidays?

Mother’s Day—which hits the calendar on Sunday, May 12, this year—isn’t the only standout event in May. From Teacher Appreciation Week and the epic clash of lightsabers on Star Wars Day to the enchanting journey through the wizarding world on International Harry Potter Day, there’s something for everyone. Plus, May isn’t just about pop culture; it’s also Asian American and Pacific Islander Heritage Month and Jewish American Heritage Month.
