Enter your birth date, time and place above and this free calculator tells you whether Grahan dosha is present in your chart. It checks all four forms the free kundali lists: the Sun with Rahu, the Sun with Ketu, the Moon with Rahu and the Moon with Ketu. For each you see the signs, whether they share one, the house and the degrees apart. It also lists the solar or lunar eclipses nearest your birth, with their dates and how far they fell from it.
How it works
Grahan means eclipse. Rahu and Ketu are the two points where the Moon’s path crosses the Sun’s, and eclipses happen when the Sun and the Moon are near them. The calculator works out your sidereal planets (Lahiri ayanamsa, mean node) and your rising sign. If the Sun or the Moon stands in the same sign as Rahu or Ketu, that form of Grahan dosha is present, by the rule the dosha panel of the free kundali uses, so the two always agree.
The eclipses come from the event list of our ephemeris (the NASA JPL DE440 tables), which gives the moment of greatest eclipse and its type for the Earth as a whole.
Reading the result
The answer at the top says whether any form is present and names it. A table shows all four pairs with the signs, whether they share one, the degrees apart and the status the free kundali gives. If a pair is present, the calculator adds whether the Sun or the Moon is exalted, in its own sign or debilitated, and whether Jupiter’s aspect falls on the pair, which the free kundali lists as the classical softening factor for such pairs.
The eclipse list gives the nearest eclipse before and after the birth. An eclipse close to the birth is not the same as a birth during an eclipse: the calculator does not check whether the eclipse was in progress at the birth minute or visible from the birth place. The guides to the Sun with Rahu, the Sun with Ketu, the Moon with Rahu and the Moon with Ketu describe how each pair is read.
Where traditions differ
Brihat Parashara Hora Shastra (ch. 91, in R. Santhanam’s edition) speaks of birth at the time of a solar or lunar eclipse and the rites for it. Later writing widened this into Grahan dosha, the Sun or the Moon in the same sign as a node, and that wider definition is the one used here and in the free kundali. Some teachers count only Rahu, some count Ketu as well, and some look at how close the two are in degrees; the result shows the degrees for reference, but the same sign decides the verdict. Some teachers read the solar and the lunar forms quite differently, which is why the four are kept on separate lines.
What it does not do
It makes no prediction and offers no remedy. The Sun or the Moon with a node is a pattern to read with the rest of the chart and the dasha running, and many charts have it. Nothing here is a reason for worry. For the eclipses of the coming years and their local times, see eclipses (grahan) and the eclipse visibility calculator.
Frequently asked questions
↳ What is Grahan dosha?
Grahan dosha is the name later writing gives to the Sun or the Moon in the same sign as Rahu or Ketu, the two points where eclipses happen. The classical idea behind it is birth at the time of an eclipse, which Brihat Parashara Hora Shastra discusses in ch. 91.
↳ How do I check Grahan dosha in my kundli?
Enter your birth date, time and place above. The calculator checks the four forms, shows the house and the degrees between the planets, gives the same verdict as the dosha panel of the free kundali, and lists the eclipses nearest your birth.
↳ Was I born during an eclipse?
The calculator lists the nearest eclipses and how far they fell from your birth, with the moment of greatest eclipse. It does not check whether an eclipse was in progress at your birth minute or visible from your birth place, so a birth on the day of an eclipse needs that check by other means.
↳ Does the Moon with Ketu count?
Yes, as one of the four forms, as in the free kundali. Each is shown on its own line, so you can follow whichever definition your teacher uses.
↳ Does it matter how close the Sun or Moon is to the node?
Not for the verdict here, which follows the free kundali: the same sign decides it. The degrees apart are shown because many readers weigh a close pair more than a wide one, and because a pair can be close yet in different signs.
↳ Should I worry if it is present?
No. It is one pattern among many, read with the strength of the Sun or the Moon, the house and the dasha. The page makes no prediction and recommends nothing to buy.
