A lot of people don't realize that the Sun moves through the 12 signs on different dates each year. If you're born close to the border of two signs, you're on the cusp, and it could go either way. For the exact degree, look at your birth chart or have a professional draw up your chart.
These are the dates from 2011, and give you a rough estimate of the degrees. What's your sign? Find out below.Aries March 20th to April 20th

Born on the Cusp: These dates change every year, and the ones above are for 2011. Find out which sign you were born in with an ephemeris, birth chart or asking an astrologer. If you were born near the end or beginning of a sign, you were born "on the cusp." This means you're a blend of the two, and will find insights reading up on both Sun signs.
