Because May 20 is the final day of the Taurus range, individuals born on this day often feel they possess personality traits from both signs. While Britannica categorizes May 20 as the end of the Taurus period, the exact hour the sun moves into Gemini changes annually. Depending on the year of birth: * The sun may still be in the late degrees of Taurus. * The sun may have already crossed the boundary into the early degrees of Gemini. This crossover means that those born on May 20 must look at the specific year and time of their birth to determine their official sun sign. ## The Astronomical Basis for Date Shifts The discrepancy in zodiac dates stems from the difference between the calendar year and the solar year. The Earth takes approximately 365.24 days to complete one full orbit around the sun. To account for the extra fraction of a day, our calendar system adds a leap day every four years.
This leap year cycle causes the sun's entry into each zodiac sign to shift by several hours each year. Consequently, the transition from Taurus to Gemini can occur anytime between May 20 and May 21. Britannica uses the word "approximately" when defining these dates to account for this natural astronomical variation. ## How to Determine Your Sign on May 20 If you were born on the May 20 cusp, you cannot rely solely on general date ranges to identify your sun sign. To find your exact sign, you must determine the precise position of the sun at the moment of your birth. You can verify this information by following these steps: * **Obtain your exact birth time:** Check your official birth certificate or hospital records for the precise hour and minute of your birth. * **Identify your birth location:** The time zone of your birthplace is necessary to calculate the exact position of the sun relative to the Greenwich Mean Time (GMT) of the solar transition. * **Consult an ephemeris or chart calculator:** Use a reliable astronomical table or a birth chart calculator to input your birth date, time, and location. This will show whether the sun was in the final degree of Taurus or the first degree of Gemini at your time of birth. By using these specific details, you can confirm whether you fall under the grounded influence of Taurus or the communicative influence of Gemini.
