Sun, Moon, Ascendant – The Big Three – If Today Is Your Birthday

Sun, Moon, and Ascendant Calculator

These days, people don’t only ask for your Sun sign…they also want to know your Moon and Ascendant signs, and sometimes more.

If you’ve been asked for astrology’s “Big Three,” your Sun, Moon, and Ascendant signs, use the following calculator to determine them. It’s easy since it gives you only the answers you need, although we’ve also thrown in Mercury, Venus, and Mars signs in case you also want to know these extras.

That’s all there is to it! However, there are many more factors to explore in a birth chart. This is meant as an introduction to newbies.

If you do not know your birth time, your Ascendant cannot be determined. Guessing will not help since the Ascendant changes every hour or two. With an unknown birth time the Moon may or may not be easy to determine, depending on whether the Moon changed signs that day. Please keep this in mind if your time is unknown.

If you need help with the time zone offset, write to annie@iftodayisyourbirthday.com. With births before 1970, these calculators may not always know the nuances of DST in some locations, but it’s excellent for births after 1970, so there’s no need to adjust for daylight saving or summer time.
