What is a solar return?
The moment each year when the Sun comes back to the exact degree it held at your birth. It is your birthday by the sky rather than the calendar, and can fall a day either side. Some astrologers cast a whole chart for that instant and read it as the year ahead.
Where you see this in OrbHeaven
Your own chart is calculated from your birth details, and this definition is written out again there with your numbers in it rather than in the abstract. The chart, the glossary and thirty days of dated timeline are free, and nothing here is charged per question.
About a minute. Birth time optional, and no account until after you have seen it.
The sky moving
Everything that happens after you are born, which is where dates come from.
