Are you certain about your Sun sign?
Many publications indicate fixed dates for the Sun entrance in each sign of the tropical system; these dates do not normally coincide when you verify different sources and that confuses people with little astrological knowledge.
The fact is that the dates when the Sun enters each sign are different every year; factors that determine the actual dates include the occurrence of leap years, as well as the earth's precession.
I indicate below the dates the Sun entered each sign during 2005 to exemplify this explanation, considering Greenwich Mean Time (GMT):
| Aquarius | 19 Jan, 23h 23m | 18 Feb, 13h 32m |
| Pisces | 18 Feb, 13h 33m | 20 Mar, 12h 33m |
| Aries | 20 Mar, 12h 34m | 19 Apr, 23h 37m |
| Taurus | 19 Apr, 23h 38m | 20 May, 22h 47m |
| Gemini | 20 May, 22h 48m | 21 Jun, 06h 46m |
| Cancer | 21 Jun, 06h 47m | 22 Jul, 17h 41m |
| Leo | 22 Jul, 17h 42m | 23 Aug, 00h 46m |
| Virgo | 23 Aug, 00h 47m | 22 Sep, 22h 33m |
| Libra | 22 Sep, 22h 34m | 23 Oct, 07h 42m |
| Scorpio | 23 Oct, 07h 43 m | 22 Nov, 05h 15m |
| Sagittarius | 22 Nov, 05h 16m | 21 Dec, 18h 35m |
| Capricorn | 21 Dec, 18h 36m | 20 Jan, 05h 15m |
As you can see in the table above, the Sun entered Aquarius on January 19th, 2005 at 23h 23m (Greenwich Mean Time). However, the Sun entered Aquarius on January 20th, 2006 at 05h 16m (Greenwich Mean Time). This explains why some people may be wrong in thinking they know their sun sign.
