What are the zodiac date ranges?

Each sign covers about a month, for example Aries runs March 21 to April 19 and Taurus runs April 20 to May 20. The tool uses these common boundaries.

A cusp is a birthday that falls near the boundary between two signs. This calculator assigns the standard sign for the exact day you enter.

Is this the same as the sidereal or Vedic sign?

No. This tool uses the western tropical zodiac. Sidereal systems such as Vedic astrology use different date ranges and can give a different sign.

About the Zodiac Sign Calculator

The Zodiac Sign Calculator finds the western, or tropical, star sign for any birth date. It returns the sign together with its element, quality, ruling planet and traditional birthstone.

The twelve signs run from Aries through Pisces, each covering a fixed range of dates. The calculator uses the common date boundaries, so a birthday on a cusp date maps to the standard sign for that day.

This is a fun, informational tool for horoscopes and birthday cards. It works entirely in the browser and does not store the date you enter.
