And just like that we have arrived in the buzzy, talkative changeable season of Gemini! Please do be aware that I work with the sidereal zodiac, which considers astrology from the actual placement of the stars in the current time. You can check this out for a quick 101 on Sidereal Astrology. Sidereal Gemini - June 21st to July 17th The Sun actually rises in the constellation of Gemini from 21st June through to 17th July. Gemini is a pretty ‘average’ sized constellation so its season runs for almost 4 weeks. And, yes if you read up about sidereal astrology, these dates are not set in stone, over almost three quarters of a century the dates will change in accordance with precession. So Who Needs to Really Read this? People who are born between June 20th (NB see above comment about the dates changing; what this means is that depending on how old the person is they may have been born into Gemini season even if they were born on the 20th June and not the 21st) and July 17th. Being born between these dates means that your ‘Sun’ sign is in Gemini and you identify as a Gemini. You most likely see yourself as curious, quick, witty and fun! People who know their astrology chart and can identify that either their Moon or their Ascendant (Rising) is in Gemini.
