Solar Return Calculator
A solar return is the exact moment the Sun comes back to the degree it held at your birth — your astronomical birthday. It drifts about six hours later each calendar year and snaps back on leap years, so it rarely lands at the instant of your party. Enter your birth date and we'll compute a decade of your returns to the minute.
What a solar return is
The Earth takes 365 days, 5 hours, 48 minutes and change to carry the Sun back to the same place on the zodiac. Calendars round that to 365 and patch the difference with leap days, which is why your astronomical birthday wanders around your calendar one. The return instant is pure astronomy — the same ephemeris data NASA navigates by, bisected to the minute.
Astrologers cast a chart for that instant and read it as the year ahead's tone — the solar return chart. Its houses depend on the exact minute and where you are when the return happens, which is why the precise time is worth knowing rather than assuming your birthday at noon.
