Your Moon is the emotional weather of the chart — and it probably isn't in the sign you think. Measured against the real constellations, most Moons land one sign back from their tropical position. This calculator shows both, plus the draconic Moon as a third layer.

Five systems. Your composition in 60 seconds.
Sidereal isn't one system. Vedic astrology uses the Lahiri ayanamsa: twelve equal signs shifted by a fixed offset. True Sidereal uses the real IAU constellation boundaries, unequal widths and all. Near a boundary the two can put your Moon in different signs.
This calculator computes True Sidereal — the Moon against the sky as it actually is — and shows your tropical Moon beside it. The Moon moves fast, about a sign every two and a half days, so your birth time settles boundary days.
The two zodiacs measure from different anchors. Tropical measures from the seasons; sidereal from the stars — and the two have drifted about 24 to 31 degrees apart. Most people's Moon lands one sign earlier in sidereal, sometimes two near a boundary.
Not always. Vedic astrology uses the Lahiri ayanamsa — twelve equal signs shifted by a fixed offset. This calculator uses True Sidereal: the real, unequal IAU constellation boundaries. Near a boundary the two systems can disagree, and this page tells you what it's actually using.
It helps. The Moon changes signs about every two and a half days, so on most dates the sign is certain from the date alone — but if you were born on a boundary day, the hour decides it. The calculator uses your exact time when you have one.
Yes. Your Moon in all three layers — tropical, true sidereal, and draconic — plus the complete chart is free, with no account or payment needed.
