To determine your Zodiac sign, Modern Western Astrology looks at the 3 most important factors:
- Your date of birth
- Your place of birth
- Your time of birth
The change of sign does not happen precisely at midnight. The exact time when the Sun switches signs also depends on your location.
For example, in 2019 the Sun entered Virgo on August 23rd at 6:02 AM in New York, but in Los Angeles, it happened at 03:02 AM. In 2020, since it was a leap year, everything shifted one day (after February) and the Sun changed from Leo to Virgo on the 22nd of August at 11:45 AM in New York and 8:45 AM in Los Angeles.
The dates for the “beginning” of a new Zodiac sign are the dates when (most of the years) the Sun changes signs. Thus, by providing specific time and location you help us determine where the Sun was positioned at the exact moment of your birth.
