As for celebrations...
There was supposed to have been a big party last Sat. at JHU sponsored by the region's CSSAs (Chnz Student and Scholar Associations on various campuses).
Next Sunday, DC Chinatown will hold it's annual parade (2pm-5).
If you want to see something sooner, you could go to Philly chinatown. They're having parades this weekend (jan 28 & 29) and the following 2 Sundays (Feb 5 & 12). They must like marching, a lot!
