What is Sahasra Chandra Darshan?

Sahasra Chandra Darshan (Sanskrit: सहस्र चन्द्र दर्शन, "seeing a thousand moons"), also called Shatabhishekam or Sahasra Purna Chandrodayam, is the Hindu celebration of a person witnessing their 1000th full moon. Because one full-moon to full-moon (synodic) month averages 29.53 days, 1000 full moons span roughly 80 years and 10 months — so the ceremony falls in a person's 81st year.

How this calculator works

It finds the first full moon after the date of birth, then the exact date of the 1000th full moon (Sun–Moon opposition) using the Lahiri sidereal ephemeris.
It shows the age on that day and the tithi, lunar month and nakshatra of that Purnima.

The milestone is computed astronomically rather than by a fixed age, so it accounts for the extra lunar months (Adhik Maas) that occur over a lifetime. Families usually hold the Shatabhishekam ceremony on an auspicious day around this date.
