Nowruz celebrations

Nowruz, the Iranian new year, falls on the spring equinox, but some groups are getting an early start on celebrations this weekend. The fifth annual Norooz Market at the Brookland Arts Walk includes more than 40 vendors selling pottery, jewelry, art and Iranian pastries, among other offerings, while the afternoon also includes performances by musicians including Aida Shahghasemi and the National Symphony Orchestra’s brass quintet. ( Saturday from 2 to 6 p.m. noroozmarket.com. Free.) The National Museum of Asian Art’s annual Nowruz Family Day has attractions for all ages, from storytelling and crafts — including saffron egg painting — to curator tours of exhibitions. Persian food will be available for purchase. ( Sunday from 11 a.m. to 4 p.m. asia.si.edu. Free.)
