What this tool does
This calculator works out your Moon sign, the sign the Moon was in when you were born, and the phase of the Moon at your birth. Both are calculated astronomically, and the written reading explains what your Moon says about your emotional needs, how it works with your Sun sign and how to look after yourself in a way that suits it. You also get a chart wheel of the planets on your birthday.
When to use it
Use it if you know your Sun sign but feel it only tells half the story. In astrology the Moon describes your inner, emotional side: what you need, how you react and what makes you feel at home. It works from your date of birth alone. The Moon changes sign every two to three days, so on some birthdays it moved from one sign to the next; if that happened on yours, the tool tells you and explains both, and a birth time settles it.
How it works
You choose your date of birth and, if you know them, your birth time and town. The tool calculates where the Moon and Sun were, works out the Moon phase from the angle between them, and checks whether the Moon changed sign during the day. With a time and place it also adds your rising sign and the house your Moon falls in. Place names come from GeoNames.
