Friday: Need a quick idea for a date night? How about the Freer and Sackler's first City Nights Open House? The galleries will stay open late to preview two new art exhibitions: "An American in London: Whistler and the Thames" is one of the biggest collections of the works of Whistler in decades, while "Kiyochika: Master of the Night" shows that artist's woodblock prints, made in Tokyo. The museums will open their courtyard and offer entertainment and curator-led tours of the exhibitions; food trucks will be on hand if you get hungry. Admission to the event, which begins at 5:30 p.m., is free.

Friday-Saturday: The chance to take in the views from the National Cathedral's tower, which is rarely open to the public, is only one of the reasons to visit the annual Flower Mart. Another reason: Is there a surer sign of spring than a sea of flowers?  You can also check out live music; puppet shows and carousel rides for children; vendors selling plants, crafts and used books; and the "Flowers Around the World" international floral display. The event, set for Friday from 10 a.m. to 6 p.m. and Saturday from 10 a.m. to 5 p.m. is free; tower climbs are $10. Read: Finding the best views of Washington.

Saturday: U Street doesn't have a block party that quite rivals H Street Festival or Adams Morgan day, but the first Funk Parade, which kicks off Saturday with a day of musical performances and a real street parade, could  change that. Bring your own djembe or tambourine, don a spangly outfit, play a flute and prepare to get sweaty: The participatory affair will be as free-form as the Meridian Hill Park drum circle. Stick around at night for free concerts at some of your favorite venues, including DC9 and U Street Music Hall.  Read and download a map of the parade route: The Funk Parade: What you need to know about Saturday's festival on U Street

Saturday: Get a little zen after a hectic work week with 3,000 fellow yogis and yoginis with Yoga on the Mall, which marks the end of D.C. Yoga Week. Bring your own yoga mat and water. The free, family-friendly event begins at 10 a.m. at Constitution Gardens near the Vietnam Veterans Memorial, and continues through noon. RSVP for the event on Facebook.

Saturday: Opera in the Outfield, the Washington National Opera's annual simulcast at Nationals Park, is one of the top free events of the year: Grab a hot dog, slip off your shoes and  go to the opera, all in one night. This year's event features a performance of Mozart's "The Magic Flute," broadcast live from the Kennedy Center on the first night of the opera's run. The three-hour show is performed in English, with stunning, fantasy-driven sets and costumes by Japanese-American artist Jun Kaneko. Gates open at 5 p.m.; get there early for admission to the outfield, which is by wristband only. Seating in the stands is open.

Saturday: "Dream," a faintly country-tinged tune recorded on the legendary Blue Note Records in 2008, introduced the world to songbird Priscilla Ahn. The video racked up millions of views on YouTube, but didn't begin to get at the depth Ahn is hiding beneath her delicate falsetto. The singer's third album, February's "This Is Where We Are," grinds harder, incorporating keyboards and pounding drums in an expression of ear-friendly electro-pop that, at its poppiest, recalls Lykke Li and, at its most experimental, the late, great Broadcast. See more music to catch this month: Iggy Azalea, Wye Oak and more top May concerts.

Saturday: Contemporary Wing, the gallery without walls launched by former Irvine Contemporary gallery director Lauren Gentile, returns to its 14th Street space for the first time in months with a new exhibition, "Friends With Benefits," a group show that will feature work by Tim Conlon, Baltimore's Gaia, John Tsombikos (the erstwhile BORF), Sonya Clark and several others with local ties.  The show, which runs through May 31, opens Saturday with a reception from 6 to 8 p.m.  Free.

Saturday-Sunday: With the weather shaping up to be pleasant this weekend, sampling wines and looking out over the waters at the annual National Harbor Wine and Food Festival sounds like an ideal way to pass a day. Tickets (prices vary) include unlimited samples of food and wines, and cooking demonstrations from well-known area chefs including Mike Isabella and Victor Albisu.

Sunday: Art Whino is marking Cinco de Mayo in one of the most unusual ways we've seen so far: The gallery is bringing in masked lucha libre wrestlers Pequeno Pierroth, Sangra de Aguila, Hijo de Dr. Wagner, Hijo de La Park, and the Caveman to battle it out -- okay, perform demonstration rounds -- at Fairgrounds. Also on tap at El Mundo de Los Luchadores will be Mexican street food, music from Escarioka, live mural painting, and an art exhibit. Tickets are $20 and available through Living Social
