Which Yearly Cycle are you in?

Each year, on January 1st, we enter a new numerological cycle which defines a distinct theme for the next 12 months. A simple calculation lets you know which cycle you are in during any year. Just add the numbers in your day and month of birth to the numbers in the current year. 

Example Birthday
December 29
Month = 12
Day = 29
Year = 2008
(The year must always contain four digits)
1+2+2+9+2+0+0+8 = 24.
Keep adding until a single digit is obtained. 2+ 4 = 6 

In this example, someone born on December 29^th ,
will be in the 6 yearly cycle throughout 2008.

The yearly cycles run from January 1st to December 31,
(NOT from birthday to birthday)
