Moon Sign Calculator
Use this moon sign calculator for your Indian Vedic Moon sign (Janma Rashi), not your Western sun sign. Add birth time and city when you can, so we place the Moon clearly.
A date alone uses a noon estimate. Near a rashi or nakshatra boundary, time and city matter. The Moon moves fast.
Example: one real birth date
With only July 18, 2023, this calculator estimates the Moon at local noon: Karka rashi, nakshatra Pushya, pada 2.
A birth time near an edge can move the rashi. The Western sun sign that day is Cancer.
How we calculate
Indian Vedic Janma Rashi comes from sidereal Moon position using the Lahiri ayanamsa. Ayanamsa is the offset between tropical and sidereal zodiacs. Sidereal means star-based. With only a date, we estimate the Moon at local noon. Birth time and city work better near rashi or nakshatra boundaries.
When the Moon position is clear, we also show nakshatra and pada (quarter). This matches the Indian Vedic card in the seven-tradition reader.
- Input: birth date; time and city strongly recommended
- Source: Lahiri sidereal math in the app
- Output: Moon rashi, nakshatra, and pada when available
- Different from tropical Western Moon or sun sign
Why Moon matters in Jyotish
In Indian Vedic astrology, the Moon sign is close to day-to-day mind and mood. Nakshatra is a smaller Moon zone. Most Western sun-sign pages never mention it.
Moon sign isn't sun sign
Your Western sun and Indian Vedic Moon rashi use different math. Plenty of people are something like Libra sun, Kumbha moon. Both can show up together in the full multi-tradition reading. You do not have to pick a favorite.
Frequently asked questions
Do I need birth time?
It is strongly recommended. The Moon moves quickly. Without time we estimate from local noon. Time plus city is better near sign changes.
Which ayanamsa do you use?
Ayanamsa is the offset between tropical and sidereal zodiacs. We use Lahiri sidereal math for Moon longitude. That is the same method used in this app's Indian Vedic path.
