What the Solar Return Is
The solar return is the oldest of the annual techniques: the moment the Sun crosses the exact longitude it held at your birth, the sky of your astrological birthday. The return happens once a year, within a day of your birthday but rarely on it, because the tropical year runs 365 days and a quarter and the moment drifts by about six hours each year. The tradition casts the chart of that moment and reads it as the theme of the twelve months ahead.
The return chart is read against the natal chart: the natal is the room, the return is the year's weather in it. The Sun of the return sits on your natal Sun by definition, so the year's core theme is always a return to yourself; what changes is everything around it, and the most readable layer is the Moon. The Moon of the return shows the emotional climate of the year: what you will feel your way through, what needs tending, what nourishes.
How to Read Yours
The calculator finds the exact return moment for your birth date and gives the Moon's sign at that moment, with the character of the year that follows. Read it as the weather, not the forecast: a return Moon in Aries is a year of starts, and the gift is the courage to begin; a return Moon in Scorpio is a year of depth, and the gift is the letting go. The natal chart beneath it never changes: the return describes how the fixed pattern will be lived this year.
For a fuller reading, cast the whole return chart: the planets of the return in their signs, the aspects between them, and the houses they fall in, counted from the return Ascendant. The Natal Chart Calculator on this site can cast the full chart for the return moment. The reading here gives the anchor: the Moon, the emotional signature of the year, and the sign that colors it.
Frequently Asked Questions
What is a solar return?
A solar return is the moment each year when the Sun returns to the exact longitude it occupied at your birth: your astrological birthday. The tradition reads the chart of that moment as the theme of your next year, and the Moon's sign in that chart as the emotional weather of the year.
When is my solar return?
Your solar return happens within a day of your birthday, but not necessarily on it: because the tropical year is 365 days and a quarter, the exact moment drifts by about six hours each year. The calculator finds the precise moment when the Sun returns to your natal longitude.
What does the Moon in my solar return mean?
The Moon in the solar return chart shows the emotional climate of the year: what you will feel your way through, what needs tending. A return Moon in Aries is a year of starts, in Taurus a year of building, in Scorpio a year of transformation. The reading above gives the character of the year by that sign.
How is the solar return chart different from the natal chart?
The natal chart is the sky of your birth, fixed for life. The solar return chart is the sky of your astrological birthday, cast each year: it describes the themes of the coming twelve months against the background of the natal pattern. The natal is the room; the return is the year's weather in it.
When does my solar return year begin?
The solar return year begins at the exact moment of the return and runs until the next one, roughly a year later. In practice, astrologers read it as the year from one birthday to the next, with the return moment marking the change of theme.

The return moment is computed with the astronomy-engine library (VSOP87 solar position, exact search for the natal longitude). The Moon of the return is given in the tropical zodiac. The readings follow the consensus of the astrological tradition on the solar return technique.
