If Earths History is comperessed in a callender Year (i.e. 5 billion Years= 12 months), if we ignore the residual life of earth, since none has seen tomorrow. Anyway, Complex organism came around 150 million years back, i.e. in calender it would be 16th december.

Depends on your definition of complex. If you mean vertebrates it would be at about 3 minutes to midnight. Human beings about two seconds to midnight. (Both of those on December 31, by the way)
