The 30 best things to do in D.C. this weekend and next week

Don’t be surprised if you see Pikachu, “Demon Slayer” or “KPop Demon Hunters” wandering around downtown this weekend: Otakon, the annual celebration of Asian pop culture, is taking over the Walter E. Washington Convention Center. Logan Circle and Middleburg host huge sidewalk sales for those who would rather hunt bargains than demons. There are outdoor movies in Bethesda, at the Library of Congress, and on the pitch at Audi Field, while county fairs and carnivals touch down in Prince William and Fairfax. Whether you’re looking for dancing, a Black book festival, clothing swaps, outdoor concerts or foreign films, there’s something around D.C. Want to get out of town? Road trip to a sunflower festival.
