Solar return calculator
Find the Sun’s return to its natal longitude around a chosen birthday and inspect the resulting chart for an explicitly selected location.
A solar return is the moment when the Sun reaches the same tropical longitude it had at birth. It usually falls near the birthday, but not necessarily at the same clock time or even on the same civil date. This tool calculates that moment and its chart.

How to use this tool
Enter the birth details and the birthday year you want to inspect. The calculation finds the nearby return rather than assuming midnight on the birthday. Coordinates determine the return chart’s local horizon and houses; they do not change the geocentric moment of the solar return.
How to read the result
Read the exact instant separately from the chart constructed for a location. Changing the location changes the horizon and houses, while the target solar longitude is the same. The year means the birthday being considered; a January birthday can have its return in late December of the preceding civil year.
Method and limits
Dates and numerical house limitations match the full natal tool. The result is not an annual prediction and does not tell you where to travel to guarantee a better year. An incorrect birth time remains an input uncertainty that no return calculation removes.
The calculation uses Astronomy Engine 2.1.19 and, where applicable, the project’s offline time-scale and house geometry modules. Mathematical positions and traditional interpretation remain separate.Read the full methodology.
