If you don't do the jargon, what you may think of as your 'birthday', in astrological language gets described as your 'Solar Return' (i.e. the Sun has returned to the same place in the sky as the day you were born). It happens once a year, and some people consider it important.
Jupiter Return happens about once every twelve years, and most people don't notice it, or know about it, or care. Today, it has returned to the exact same place in the sky...for the sixth time since I was born.
As it happens, I checked back, and last time Jupiter returned to my birth point, I found myself in the middle of an online learning course, entitled "Tale of The Tribe" with the inestimable Robert Anton Wilson.
I guess it bodes well for expanding my knowledge at this time.
