### 12/12/12: A Very Good Day

(12/12) / 12 = 0.08333333333

For those people who are attracted to the special significance of numbers, today, 12/12/12, marks the day of the last sequential date on our present calendar for the next 89 years (it won't happen again until January 1, 2101).

This Century's Final Repeating Date:

The tropical year is identified as "the time it takes the Sun to appear to travel around the sky from a given point in the tropical zodiac back to that same point in the tropical zodiac." Of course, this value depends on where in the Earth's orbit one begins the measurement of one revolution about the Sun (John Dee emphasized this point as early as 1582 C.E.).

For our purposes, rather than assign a different value to different date in an arbitrary unit of measurement (i.e., any of our present-day calendars that do not precisely mark the beginning of our planet's existence), let's just go with the Gregorian calendar and for argument's sake say that today is 12/12/12 C.E.

In 2012 C.E. (a Wednesday), I will spend the day in Paris with my children reveling in the resplendence of our common global heritage.

Whether or not you assign increased significance to today - 12/12/12 - any day whereby multitudes of people take notice, pause, and contemplate a deeper, potentially more signifiant meaning to the world, to life, and to our place amid it all, is for all practical purposes:
