Western zodiac sign calculator
People type a birth date and expect a clear Western tropical zodiac sign plus the date window that sign occupies on the civil calendar.
Run — free
Runs in your browser. Free, unlimited — your data never leaves this page.
This western zodiac sign calculator maps month and day to one of the twelve tropical signs using a fixed cusp table that matches the ranges printed on countless charts and profiles—Capricorn wrapping the year end, Aries opening at the spring equinox window in popular lists, and so on—then returns the English sign name, Unicode glyph, classical element and modality, and both a readable date range string and structured start and end month-day objects. The path is pure integer validation and comparison: no ephemeris download, no wall clock, and no timezone surprises, so the same birth month and day always produce the same JSON in tests and in production. Invalid combinations such as month thirteen or April thirty-first fail with invalid input and are not charged. The browser widget runs free on your device; the prepaid API charges $0.002 per successful item when apps and backends need the same contract.
