Zodiac sign finder

Western signs come from the conventional tropical boundary table. The sun's exact sign changes drift by about a day from year to year, so a date on the first or last day of a range borders two signs and the page says so instead of pretending certainty. The Chinese animal follows the lunar year: Chinese New Year falls between January 21 and February 20, so a birth date before the new year belongs to the previous animal, and the table of new year dates covers 1900 to 2100.
