The clock moved from one year to the next. I am not sure what it really means. If we think in geological time there is no difference between 2011 and 2012. There is not much to the change other than our calendars we use to tick off the time. This line has been drawn.
The Japanese used to celebrate the new year according to the phases of the moon, but in the Meiji period they decided to follow the Gregorian calendar. Why? Did they want to be more like the west, or less like the other asian nations?
It is just a point we use to attempt changes in our lives. In that respect it is a positive, however, we should be striving for these changes for frequently. The process of observation, reflection, and change should be ongoing, and not decided by a date on the wall.
Look out into the known unknown and see what there is to be seen.
