What it does

Finds your , the sign the Moon was in at birth, with its degree, nakshatra and strength, and flags when the sign is uncertain without an exact birth time.

Why it matters

In the Vedic system the Moon sign is the main 'sign': daily horoscopes, Sade Sati, many matching rules and the dasha timeline all start from it.

How it is worked out

  1. The astronomy engine computes the Moon's apparent position as seen from your birth place at your birth moment (checked against NASA JPL reference data).
  2. The (about 24°) is subtracted to move from the seasonal to the .
  3. Sign = longitude ÷ 30°. Nakshatra = longitude ÷ 13°20′, pada = the quarter within it. House (whole-sign) = count of signs from your .
  4. The sign is compared with the traditional tables (exalted, own, friend, neutral, enemy, debilitated).

How to read your result

  • Sign and degree: the planet's exact place on the zodiac belt. Near 0° or 29° it is close to a boundary and is the first thing to change if the birth time is off.
  • Nakshatra and pada: the finer star-station; the nakshatra's own ruler also matters in the tradition.
  • House: which life area the planet occupies. It needs your birth time, because the houses depend on the rising sign.
  • Dignity, retrograde and combust flags: tradition reads them as the planet being comfortable, inward or overpowered by the Sun's glare.

What it cannot tell you

The Moon moves about 13° a day, so its sign changes every 2¼ days and its nakshatra daily. This is why the birth time matters most for the Moon: a few hours can change the nakshatra or even the sign. Meanings are traditional symbols for reflection, not predictions.
