What Is a Birth Sign Calculator?
A birth sign calculator helps you identify the astrological sign associated with your birth date. In most cases, people are referring to the Western zodiac, which includes signs like Aries, Taurus, Gemini, and so on. Some people also like to pair this with the Chinese zodiac, which is based on birth year.
This calculator gives you both in one click, so you can quickly discover your signs without memorizing date ranges.
