When does the Chinese new year festival start and end ?

Evey year is different, but in 2009, Chinese nunar new year started from Jan 26 2009 and will end in Feb 4 2009.

the chinese New Years eve was on 25th january, and new years day therefore was 26th january, however, celebrations last 10 days, and im still on holiday until the 6th february, since 22 january! but companies differ, and friends of mine are going back to work on monday already. this is my first year in china, so not too sure when it officially ends, but most shops were still closed today and alot of the chinese people i know are still in their home villages

Are you talking about CCTV's Annual Spring gala? That's over now, but you can watch parts of it on Youtube from the user "cctv". :)

people usually celebrate the new year up until the 15th day of the first month, that'll be Feb 7, though most people (in China) will be back to work after this weekend
