Zodiac sign by birthday
Pick your birth month and day to get your Sun sign from the standard tropical table. If your birthday is on a cusp date, the result tells you which two signs are involved and where to check the exact time.
Uses the same date table as the zodiac calendar and the home-page finder.
Exact sign-change times
For a birthday right on a cusp, the year matters. The year calendars list the exact moment the Sun enters each sign, in UTC and converted to your device's time zone: 2026, 2027 and 2028. The same data is available as CSV and JSON downloads.
