What is a Moon Sign?

A moon sign is where the moon is when you were born. Most people are familiar with their sun (or star) sign, and may not realise that their moon sign also has great significance. The sun sign is active in your life, whereas the moon is more reactive; the moon can be the source of our emotional desires and our deeper inner life, whereas the sun determines the more immediately apparent aspects of our personality. Nurturing the moon is key to understanding the inner truth of who we are.

Watch astrologer David Wells explain the significance of moon signs:

If the moon sign is so important to my horoscope, why might I not know my sign?

Unlike the sun sign, which is based around 12 easy to remember, month-long cycles, the moon sign changes around every 2.5 days. So traditionally you need a lot of complicated tables to work out your moon sign precisely. The calculator to the left makes this a lot easier! Even if you don't know your exact time of birth, just leave the time blank and the calculator will offer you both moon signs to read about if the moon changed on your birthday.

How can my sun sign and moon sign work together?

Understanding your sun and moon sign in conjunction is absolutely critical to discovering your strengths, weaknesses and inner conflicts. For example, although you may be an extroverted Leo sun sign, your inner self of the moon might be a Scorpio moon that craves peace and quiet. This might lead you to hide your emotions, despite your need to be in the spotlight. Rather than 12 interpretations of sun signs, there are now 144 more precise combinations of signs to help you understand your love life, your career and your future.
