On June 14, President Donald Trump will celebrate his 80th birthday on the ground with a UFC cage fight, but in the celestial sky he will be a Gemini battling cosmic forces.

Gemini is the astrological zodiac sign for people who are born on June 14 ― and if you believe in astrology, which is the art and science of interpreting the planets and constellations, everything about Trump’s personality can be traced to their movements in the sky on the day he was born. In astrology-speak, where every star and planet is located on your birthday is your “natal chart.”

“He was actually born on a full moon eclipse, so that is indicating he’s a person who needs a lot of mirroring or outside input. He looks to the outside to feel fulfilled,” said Kristina Martin, who co-hosts the podcast “It’s a Sign! The Art of Alignment.” “It can also make him pretty sensitive and perhaps prone to temper tantrums.”

In astrology, every birthday is also the time of your solar return, an astrologically significant event where the sun returns to where it was on your birthday, and a time where astrologers will look at where celestial placements are currently in the sky to determine the energy of your year ahead.

“Everyone’s solar return is important because it gives us a blueprint of the next year of their life,” said astrologer Lisa Stardust.
