May Day, usually celebrated on the first day of May, is an ancient northern hemisphere spring festival. For a May Day bash at the William Paca House, we’ll first listen to Little Gray Rabbit’s May Day, and then we’ll do crafts and other activities to jubilantly celebrate the spring. 10:00-11:15 a.m. Reservations required. Cost: $8 per child for HA Members and Volunteers, $10 per child for Non-Members

Grab your favorite dockside seat in America’s Sailing Capital to watch some 130 crews compete in midweek races that involve sailing around several marks in the Chesapeake Bay before heading back to Spa Creek for a finish in front of the Annapolis Yacht Club. Grab your seat at Annapolis City Dock or the Spa Creek Bridge for the best views. Every Wednesday evening through August 31. 6:15-8:00.
