About Hindu Panchang Tithi Calculator

A tithi is each twelve degrees of elongation between the Moon and the Sun, so the tithi number is the elongation divided by twelve, with the first fifteen forming the waxing paksha. Because tithis depend on true rather than mean lunar motion, they can run from about 19 to 26 hours, so this mean-motion estimate can differ from a published panchang.

Formula

Tithi

tithi = floor(elongation in degrees / 12) + 1, where elongation = moon age / synodic month x 360

Worked example

With the default values below, Hindu Panchang Tithi Calculator returns Tithi number in the lunar month of 23. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • A mean-motion approximation. Use an ephemeris-based panchang for ritual timing.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Hindu Panchang Tithi figure worked out?

tithi = floor(elongation in degrees / 12) + 1, where elongation = moon age / synodic month x 360. A tithi is each twelve degrees of elongation between the Moon and the Sun, so the tithi number is the elongation divided by twelve, with the first fifteen forming the waxing paksha.

Why does this matter?

Because tithis depend on true rather than mean lunar motion, they can run from about 19 to 26 hours, so this mean-motion estimate can differ from a published panchang.

What do I need to enter?

Enter date, hour of day in utc. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
