Find your birth star and its pada

Last updated 25 October 2026

Enter your date and time of birth to see the nakshatra the Moon occupied when you were born, with its quarter (pada), ruling planet and deity. Further down: how the star is found, the three jobs an astrologer gives it, why the pada matters, and what to ask in a consultation.

How the birth star is worked out

The zodiac of 360 degrees is cut into 27 equal mansions of 13°20′ each, counted from Ashwini at the start of Mesh to Revati at the end of Meen. Each mansion is cut again into four quarters, or padas, of 3°20′. The calculator finds the Moon’s position at your birth and reads off which mansion and which quarter it was in.

You give the date, the clock time and the UTC offset in force where you were born (UTC+5:30 for India). The tool turns that into Universal Time, computes the Moon’s place for that instant, and subtracts the Lahiri ayanamsa to express it against the fixed stars, as Jyotish does. The result names the nakshatra with its ruling planet and presiding deity, the pada, the sign that contains it and the Moon’s exact degree. If you do not know the time, tick the box and you get every star and pada the Moon passed through that day, with the clock time of each change.

When a time is entered and the Moon sits within half a degree of the edge of a pada (roughly an hour of its motion), the result flags it and names the star and pada on the other side, so you know the answer depends on the accuracy of the recorded time.

What an astrologer does with your birth star

For most practitioners the janma nakshatra is less a description of character than a reference point that several separate techniques start from. Three come up in nearly every consultation.

Timing: the dasha sequence

Each nakshatra is ruled by one of nine planets, in a fixed cycle that repeats three times around the zodiac. The ruler of your birth star is the planet whose Vimshottari period was running when you were born. Because the periods follow a set order and set lengths, everything after that first period can be laid out on a calendar. An astrologer who says you are “in Saturn’s period” got there by starting from your nakshatra.

Matching: comparing two stars

In ashtakoota matching, Tara, Yoni, Gana and Nadi are all judged from the two birth stars, and the South Indian poruthams lean on them even more heavily, Rajju among them. A practitioner looking at a match usually starts with the stars, then checks the exceptions the texts allow, and only then turns to the two full charts. Our guide to kundli matching consultations explains how that conversation normally runs.

Choosing dates: tara bala

When an astrologer chooses a date for a ceremony, a move or a signing, one of the first filters is tara bala: the star of the day is counted from your birth star and the count, grouped in nines, is read as supportive or unhelpful for you personally. So two people can be given different “good days” in the same week, simply because their birth stars differ.

What the star alone cannot do is describe a whole life: a great many people share any one nakshatra. A careful reader will place it within the rest of the chart: the Moon’s sign and house, the planets that aspect it, the condition of the star’s ruling planet, and the running dasha.

Why the pada is worth getting right

The quarter is not decoration. Each pada corresponds to one navamsa, so the pada of your Moon fixes the Moon’s sign in the D9 chart, which many astrologers read for marriage and inner strength. The four padas of one nakshatra therefore fall in four different navamsa signs, as the table below shows.

Padas also matter at the edges. Some matching exceptions depend on two people sharing a star but not a quarter. The last quarter of Ashlesha, Jyeshtha and Revati and the first of Magha, Mula and Ashwini sit at the junctions between water and fire signs, known as gandanta, which many astrologers like to note. And the further the Moon has moved through its star, the less of the first dasha is left, which is why the pada and the degree, not only the star, decide your dasha dates.

Questions to ask your astrologer about your nakshatra

• Which dasha was I born into, and how many years of it remained at birth?
• Is the ruling planet of my birth star well placed in my chart, and does that change how you read the star?
• My Moon is near a pada edge: which pada are you using, and what would change if it were the other one?
• For the date you are suggesting, what is the tara bala from my star, and what else made you pick it?
• In our match, which koota scores come from the birth stars, and do any of the classical exceptions apply?

If you are unsure of your birth time, sort that out before the session; our page on birth details for astrology covers where to look.
