Li Chun is a term in the Chinese solar calendar.  Li Chun, also known as Da Chun, is the first term of the 24 solar terms.  It marks the beginning of the season of spring.  But it is not the 1^st day on the Lunar Calendar which we Chinese celebrate our Lunar New Year.  In ancient China, Li Chun is the day where farmers begin their work on the field after a long rest.  

Li Chun normally falls on the 3^rd or 4^th of February of the Gregorian calendar, the calendar commonly use today. 

 Base on the lunar calendar, the year of Ox in 2009 would commence on the 26 January 2009 and ends on 13 February 2010.  This would means there is two Li Chun within the year of Ox, which falls on 4 February 2009 and 4 February 2010.  It is referred to a year of double spring.  It is an auspicious sign promising good harvest and double good news or celebrations.  

If the Lunar New Year starts after the 1^st solar term – Li Chun, it would be referred to as a blind year or a widow year, like this year of Tiger in 2010.  This year of Tiger commence on 14 February 2010 and ends on 2 Feb 2011.  In the Chinese custom, it is a bad omen of unfavorable outcome or unsuccessful year.  Chinese would avoid marriage and giving birth in a blind year.
