Everyone seems to know it's National Secretaries Week, but dancers all over the country have reason to celebrate, too. In honor of National Dance Week the YWCA at Ninth and G streets NW is holding a marathon celebration starting today at 2 p.m. (and continuing well into the night). More than 30 dance companies from the Washington/Baltimore area will participate. Dance Fest '83 will include performances, workshops, film and video displays of everything from jazz and tap to ballet and Afro-Caribbean dance. The event is sponsored by the Joy of Motion Dance Center, the YWCA Arts Program, the Metropolitan Dance Association and Diane Floyd and Saturday Company.

Among the many people tapping, leaping, swinging and plie'ing will be modern dancer Diane Floyd. "We wanted to make no artistic judgments," Floyd says. "We just wanted to include all the people who love to dance in Washington. In fact, many of the companies are bringing kids."

"The money will go for the Y arts program," Floyd adds, "which operates pretty strictly on volunteers."

Janice Gorton, the YWCA Arts Coordinator, says the festival has three purposes: "To honor the dance companies in Washington, to give smaller groups an opportunity to perform and to show the Y's capacity for bringing many different disciplines together." After the eight hours of performances, says Gorton, "There will be an open celebration for everyone who participated or who wants to come."
