Gemini dates and cusp accuracy
Date ranges are a guide. The sky is the calculation.
Gemini is commonly listed as May 21 – Jun 20, but the Sun does not enter a sign at midnight on a fixed calendar date every year.
If you were born near a boundary, use your year, local time, birthplace, and historical timezone to calculate the Sun’s longitude. Zodiaro uses the tropical zodiac and Swiss Ephemeris rather than assigning a sign from a simplified date table.
