To get the most from my horoscopes, use the horoscope maker to find your rising sign and sunsign decan.
Each decan is made up of 10º. They are divided up as follows.
Decan 1 = 0º up to (but not including) 10º Decan 2 = 10º up to (but not including) 20º Decan 3 = 20º up to (but not including) 30º
So for example if your Sun is at 9º 59′ Leo, it would still be in Leo decan 1. Decan 2 starts from and including 10º. The dates given are for the Sun signs (Ie Birthdays) these change from year to year by 1 or 2 days. The cosmic report will keep decan dates accurate for the current year, but use the horoscope maker to find the accurate day for your date of birth.
