Why “cusp” birthdays are a coin-flip
Horoscope columns print fixed dates, but the Sun enters each sign at a different moment every year. The calendar year is 365 days while the Sun’s circuit takes about 365.24, so the ingress slips about 6 hours later each year, then jumps back a day after every leap day.
Times in UTC. If you were born on one of these days, only the calculator above (with your time and place) can say which side of the line you fall on.

Questions people ask
What is my zodiac sign?
Your zodiac sign (Sun sign) is the sign the Sun was in on your birthday. The table on this page gives typical dates; for birthdays near a boundary, use the calculator with your year, time and place.
I was born on a cusp. Which sign am I?
Astronomically there’s no blend: the Sun is in one sign or the other at any instant. The boundary moment shifts by up to a day from year to year, so enter your full birth details above to get the exact answer.
Why do different websites list different dates for my sign?
Because the Sun’s entry into each sign varies by year and time zone, sites round to “usual” dates. The calculator above computes your actual birth year.
Is my sign different because of Ophiuchus or precession?
Western astrology uses the tropical zodiac, tied to the equinoxes, not the constellations. The constellations have drifted about 24° due to precession, which is what sidereal (Vedic) astrology accounts for. Tropical signs haven’t changed.
