This transit occurs once every year for everyone. It also happens on the same day each year. So if you know what degree your Uranus is in, you can easily figure out when this transit occurs for you each year. In my case, Uranus is at 29 degrees Virgo. Thus each year on the 22nd of August, I experience the Sun conjuncting my natal Uranus.
For people who are strongly Uranian, this day of the year may really stand out for you. I'm looking for feedback and more comments about this transit please.
