Zodiac sign by date

The twelve zodiac signs, with exact dates

The twelve signs of the zodiac are equal thirty-degree divisions of the ecliptic, the apparent path of the Sun across the celestial sphere. Because the calendar year does not align perfectly with the solar cycle, the precise moment the Sun enters each sign shifts from year to year. For anyone born close to one of those transitions, a standard fixed table can name the wrong sign, which is why the boundaries below are computed rather than copied.
