Free Solar Return Calculator
Once a year the Sun comes back to the exact degree it held when you were born. The chart cast for that moment — in the place you will be living — describes the twelve months that follow. Enter three details below and cast it free.
1. Birth date
Sets the natal degree the Sun returns to.
2. Birth time
Fixes the exact moment of the return and the houses.
3. Where you will be
Your location on the day changes the rising sign of the year.
Location matters: a solar return read in a different city gives a different rising sign and a different set of houses. Choose where you expect to actually be.
How to read your solar return chart
Start with the rising sign of the return. It sets the posture of the year — how you will be met, and what approach the twelve months reward.
Then find the house holding the return Sun. That house is where the year spends you: work, home, partnership, study, standing. It is the single most useful line in the chart.
Read the dominant element and modality for pace. A fire-heavy cardinal year wants initiative; a water-heavy mutable year wants patience and better boundaries.
Finish with the hard aspects. They are not punishments, they are the places the year will insist you renegotiate something.
Solar return questions
What is a solar return chart?
A solar return is the chart cast for the exact moment the Sun comes back to the degree it held when you were born — usually on or within a day of your birthday. It is read as a forecast for the twelve months that follow.
Is this solar return calculator free?
Yes. The chart, the year themes, the cautions and the full list of return placements are free and need no sign-up.
Does where I am on my birthday change my solar return?
Yes. Latitude, longitude and time zone change the ascendant and the house cusps of the return, so the same year reads differently from different cities. Some astrologers travel deliberately for this reason.
How long does a solar return chart last?
From one birthday to the next. It overlaps with transits and progressions, which describe the timing inside the year the return frames.
What should I read first in a solar return?
The rising sign of the return, then the house holding the return Sun — that house is the arena the year spends you in — then the dominant element and modality for pace.
In short
Free solar return calculator: enter your birth date, birth time and the city you will be in to cast the chart for your next birthday — rising sign of the year, Sun house, dominant element, themes and cautions.
- The return chart is a lens, not a replacement. Nothing in it overrides the natal chart; it colours a year of it.
- A return Ascendant matching a natal angle usually marks a significant, memorable year.
- If the return Moon is angular, expect the year to be driven by domestic or emotional events rather than plans.
- Write three predictions on the day you cast it, seal them, and open them next birthday.

Angles that matter
Solar returns belong to a family of techniques the Arabic astrologers called revolutions: cast a chart for the instant a planet comes back to its natal degree and read the period that follows. Abu Ma'shar and Al-Biruni describe the method in the ninth and eleventh centuries, and it passes intact into Renaissance European practice.
The technique survived because it is testable. A solar return has a hard start date, a hard end date, and a chart specific enough that its claims can be checked against what actually happened.
Modern practice added the relocation debate: because the Ascendant depends on where you stand, some astrologers travel deliberately for a birthday, hoping to buy a better year. Traditional writers read the return from the place of residence and treated the rest as superstition.

A chart cast for the exact moment the Sun returns to the degree it occupied at your birth — read as a forecast for the twelve months that follow.
When does my solar return happen?
On or within a day of your birthday, at the instant the Sun regains its natal longitude. The precise time shifts each year.
Does location change the reading?
Yes. The Ascendant and house cusps depend on where the chart is cast, so the same moment reads differently in different cities.
How long does a solar return last?
One year, birthday to birthday, with the strongest effects usually in the first four months.
