Your Birth Details
Your birth time helps place this month’s Moon in your houses. If you do not know it, I will use solar houses counted from your Sun sign.
This sets the dates and times in your calendar to your own time zone.

How I Read the Moon You Were Born Under
The Moon is the fastest-moving light in the sky. Every month she meets the Sun, pulls away from it, faces it from across the sky, and comes home again. Each of those turning points is a different kind of energy, and the moment you were born, the Moon was somewhere in that cycle.
I read your birth Moon phase as the way your soul moves through every cycle in life. Some of us are born to begin, some to build through challenge, some to see clearly, and some to finish and prepare the way for what comes next. None of them is better than another. Each one simply asks something different of you.
Then there are the lunar mansions, an ancient system that divides the Moon’s path into 28 stations, one for each night of her journey around the zodiac. Your birth mansion adds texture to your emotional nature, a symbolic thread that runs underneath everything you feel.
What This Calculator Shows You
- Your birth Moon phase. Calculated from the exact angle between the Moon and Sun when you were born, using eight phases of 45° each.
- Your birth lunar mansion. One of 28 equal stations of 12°51′ each, counted from 0° Aries.
- Your Moon sign and house. Where your emotional nature lives in your chart.
- This month’s Moon dates. The New Moon, First Quarter, Full Moon and Last Quarter in your own time zone, and which house of your chart each one lands in.
What It Is Not
The Moon is a rhythm, not a rulebook. These placements are symbolic invitations to work with your own cycles more consciously, not predictions or promises. You do not need a ritual at every phase.

- Your birth chart: calculated with the Swiss Ephemeris, the same engine behind my free birth chart: tropical zodiac, geocentric, Placidus houses and the True Node.
- The month: the Sun and Moon are calculated with Astronomy Engine, and the phase times are checked against the US Naval Observatory. Times are shown in the time zone of the city you live in now.
- Phases and mansions: eight phases of 45° measured from the Sun to the Moon, and 28 equal lunar mansions of 12°51′ each from 0° Aries. The stars named in each mansion are traditional associations, not a claim that your Moon sits on that star.
- No birth time: I use the Moon at noon and solar houses counted from your Sun sign. If your Moon could be in two mansions that day, both are shown.
