🧭 Choosing a calculation system

Panchangams aren't one-size-fits-all. Different traditions calculate Tithi, Nakshatra, and muhurtam timings slightly differently β€” sometimes by minutes, sometimes by a full day for festivals like Ekadashi. Here's what each system means, who uses it, and how to pick.

β˜€οΈ Drik Ganita β€” Modern Observational Astronomy

Calculated directly from real planetary positions using the Swiss Ephemeris with the Lahiri ayanamsa β€” the same kind of engine used by professional astronomy software. Because it tracks the sky as it actually is, it's the most accurate system for sunrise, sunset, moonrise, and moonset, and is the default in most modern digital panchangam apps.

What it computes: True geocentric positions of the Sun and Moon using the Swiss Ephemeris β€” the same engine that powers professional astronomy software. It applies the Lahiri ayanamsa (also called Chitrapaksha), which is India's government-adopted standard since 1955 and is specified by the Indian Astronomical Ephemeris. Because calculations are grounded in actual sky positions, sunrise and sunset times will match your weather app, and Tithi/Nakshatra boundaries reflect exactly when the sky transitions occur at your location.

Who uses it: The default for most modern digital panchangam apps and websites. If you're comparing against Prokerala, AstroSeek, or any app that doesn't specify a system, it's almost certainly Drik Ganita.

Gotcha: A small number of traditional institutions still associate "Drik" specifically with the Krishnamurti (KP) ayanamsa variant. If you hear someone say Drik results differ from what you see here, ask which ayanamsa they're using β€” this implementation uses Lahiri.

πŸ›• Surya Siddhanta β€” The Classical Siddhantic Method

Computes positions using the mean-motion formulas of the Surya Siddhanta, the most influential classical Sanskrit astronomy treatise. Timings follow the traditional siddhantic framework rather than the observed sky, so Tithi and Nakshatra boundaries can differ from Drik Ganita by anywhere from minutes to an hour or more. Choose it if your tradition is rooted in classical siddhantic calculation rather than modern ephemerides.

What it computes: Planetary longitudes from the mean-motion model codified in the Surya Siddhanta (the received text dates to roughly 400–800 CE, building on older material). Instead of tracking the actual sky, it counts long-period average orbital revolutions from the Kali epoch and applies the classical manda (equation-of-centre) correction. The result diverges from true positions β€” about half a degree for the Sun, up to ~4Β° for the Moon, since the classical model omits the Moon's evection and variation terms β€” which typically moves a Tithi boundary by 2–6 hours versus Drik Ganita, often enough to land an observance on a different calendar day.

Who it's for: Communities and almanac lineages that compute from the siddhantic framework. Important honesty note: there is no single "the" Surya Siddhanta panchangam β€” every traditional lineage applies its own bija (correction) constants and conventions, so two siddhantic panchangams rarely agree to the minute, and this feed won't exactly match any particular institution's published calendar either. Treat it as a faithful rendering of the classical method, and use the preview above to compare against the panchangam your family or temple actually follows.

Gotcha: For Tithi-sensitive observances (Ekadashi, Amavasya, Pournami) the siddhantic and observational boundaries can fall on different dates β€” which is why two families can fast on different days without either being "wrong."

πŸ“œ Vakya β€” Traditional Printed Panchangam

Builds on Surya Siddhanta with "Vakyas" β€” pre-computed correction tables passed down through generations of traditional almanac-makers. Many printed Telugu and Tamil panchangams sold each year descend from this tradition, so it suits households following a long-standing family or regional printed panchangam.

What it computes: Builds on Surya Siddhanta mean motions but layers in vakyas β€” pre-computed correction sequences that account for the Moon's variable speed (faster near perigee, slower near apogee). The word "vakya" means "sentence": each correction value was traditionally encoded as a memorable Sanskrit syllable sequence, attributed to the Vararuci and later Madhava traditions of South India. It let an almanac-maker produce a full panchangam by lookup and arithmetic, with no ephemeris needed.

Who it's for: Households that follow a traditional printed almanac. Many printed Telugu and Tamil panchangams descend from the vakya tradition, but publishers differ in which tables and corrections they use β€” two printed panchangams for the same year routinely disagree by 5–15 minutes on Tithi end-times. This feed implements the vakya approach as a correction layer over Surya Siddhanta; it represents the tradition's method, not any single publisher's booklet. Compare a few days in the preview against your printed panchangam to see how closely they align.

Gotcha: Vakya's lunar corrections improve on plain Surya Siddhanta for Moon-dependent timings, but it remains less precise than Drik Ganita for observable events like sunrise and moonrise. If your rule is "we follow our printed panchangam," pick whichever of Vakya or Surya Siddhanta matches it more closely in the preview.

Not sure? Drik Ganita is a safe modern default. If your family or temple follows a specific printed panchangam, use the preview above to compare a few days against it and pick the system that matches most closely β€” no two traditional panchangams agree to the minute, and that's normal.

πŸ€– Use Panchangam in AI Assistants

mcp-server-panchangam is a standard MCP server that gives AI assistants direct access to Panchangam calculations β€” ask Claude or any MCP-compatible agent for today's Tithi, a muhurta for next Tuesday, special days in the coming month, or a day-by-day comparison across a date range, and it calls the engine directly rather than guessing.
