What is a Moon Sign?

In astrology, your Moon sign represents your inner self, your emotions, and your subconscious patterns. While your Sun sign (the one most people know) dictates your outward personality and ego, the Moon sign governs how you process feelings and what you need to feel safe and secure.

How the Calculation Works

The Moon travels through the entire zodiac roughly every 27.3 days, staying in each zodiac sign for about 2.5 days. Because it moves so quickly, the Moon sign is much more time-sensitive than the Sun sign. To calculate it accurately, you need your exact birth date, time, and timezone.

Calculation Example:

  • Birth Date: June 15, 1995
  • Birth Time: 10:30 AM
  • Julian Day: 2449883.9375
  • Lunar Longitude: ~295° (Capricorn)
  • Result: Capricorn Moon
