In the 1st century, Sol didn't cross from Gemini to Cancer until June 24th. You can calculate this on Stellarium if you doubt it.

Also, Sol isn't actually in Cancer at Midsummer anymore. Check it yourself. We're actually just coming out of Taurus and entering Gemini tomorrow.

Autumnal equinox isn't Libra anymore either. We're just entering Virgo at Autumnal Equinox. And Vernal Equinox is squarely in the middle of Pisces.

So, whatever you thought your sun sign was, it's one back from that one. All the nativity progression charts you've ever done are all totally wrong.

Sorry. Anyway, happy summer. :-)
