Chinese Lunar New Year. Belgrano's Chinatown is small, but the dragon-blessing parade is a fun, intimate event that kids and adults are certain to enjoy. Beware of irresponsible firecracker users. The actual date of this holiday follows a lunar calendar. First Sunday of February.

December

El Día Nacional de Tango. Always on December 11, this festival celebrates the birth of Carlos Gardel, the world's most famous tango crooner. Avenida 9 de Julio and Avenida de Mayo are blocked off for live tango concerts and tango dancing in the street. This is Buenos Aires at its most magical.

Midnight Mass on Christmas Eve (Noche Buena). Though Argentina has little in the way of Christmas rituals, the mass at the Catedral Metropolitana is a beautiful spectacle. It is usually held at 10pm on Christmas Eve. In Argentina, December 24 is a more important day than December 25, and family dinners are held on Christmas Eve rather than Christmas Day.
