About Pūjāvāni
Pūjāvāni is the voice of devotion — puja, the worship, and vani, the voice it is spoken in. A puja has a moment, a procedure and a list: when it falls, how it is done, and what it takes. The panchangam (the almanac) answers the first, and is the deepest-built part of this — the first capability, not the whole of it.
The sacred meaning behind Pūjāvāni
The name joins the two halves of a daily practice.
Puja (पूजा) — the sacred act
Vani (वाणी) — the voice of devotion
Our mission
Nobody arrives here wondering what to keep. They arrive knowing the puja, and stuck on what comes after — whether this purnima falls on the Thursday or the Friday where they actually live, what the steps are, and what has to be on the tray. Not three errands: one puja seen from three sides, answered in one place.
The panchangam is the first of the three and the deepest built: computed from the Swiss Ephemeris for the place you give it, not transcribed from a calendar printed for one city in a year that is not this one. Indian astronomers and mathematicians worked this out over millennia; computing it rather than copying it is what keeps a household’s own answer correct.
What we offer
The three questions a puja asks, and the two engines that read a person and a place.
How it is done
The vidhi as ordered steps, with the mantra where the tradition gives one, and the samagri list beside it. Every procedure here is a draft — written in-house, and none has yet been read by a practising purohit — so a page shows how a puja is done, not how it must be done.
When it falls
The five limbs — tithi, vaaram, nakshatra, yoga, karana — with the instant each one ends, computed for your place against its own sunrise. Beside them: muhurtham windows for the ceremonies the engine holds rules for, gruhapravesham timing, eclipses with their local visibility, and festivals placed by the shastra rule that governs each, with the rule shown.
What it takes
The samagri list — quantities, and whether an item is required or kept by family custom. On a puja from the corpus it is split the way a household needs it: what a kit covers, what you keep ready at home, and what is optional. What is left is your shopping list.
Jatakam — a reading about a person
A birth chart, Ashta Koota matching across all eight kootas, and a Hindu-birthday reading — each free to preview, no account. An account carries the same reading further: the divisional charts, the Vimshottari periods, Ashtakavarga and the six-fold strength. It also keeps the charts you return to.
Vaasthu and IKS — a reading about a place
The classical spatial canon, open to read: sixteen-zone angular slicing, thirty-two entrance padas, forty-five Mandala Devatas, the Ayadi Shadvarga constants, Vrikshayurveda planting zones, circular-flow Pashu Goshala design, and where a shastra rule meets a municipal building code. The tables are public; auditing your own plan against them needs an account.
Booking a purohit, so a household can keep a puja end to end from one place. The samagri half is already open — the shelf is priced and orderable — and booking is owned work that does not carry a date.
Astronomical engine & precision
How the timing question — when it falls — is actually answered.
Swiss Ephemeris astronomical engine
Every position and every event timing is computed by the Swiss Ephemeris rather than read off a printed table, so a figure can be traced back to the ephemeris that produced it. What has and has not been checked against a published almanac is set out in the verification chapter under Reference.
Drik Siddhanta observational astronomy
Following the Drik Ganita tradition, all five limbs use true observed positions rather than mean-motion approximations. A transition instant is found by root-finding on the real longitude difference, not by interpolating a daily table.
Canonical shastra rules
The rules that decide which day a puja belongs to — Arunodaya, Aparahna, Sayahna, Pradosha and Nishitha muhurthams — are modelled with explicit boundary conditions for Smartha and Vaishnava practice.
Global geospatial coverage
Topocentric parallax corrections and atmospheric refraction models, over a bundled gazetteer of 8,285 cities — and any other place by its coordinates, which is what the calculation actually needs.
Why two almanacs can disagree
A festival is not placed by arithmetic alone. The shastra rule for each one names which qualifying instant decides — sunrise, the afternoon, dusk, the pre-night hour, or midnight — and one sampradayam (a household’s own line of practice) may not keep the same rule as another. Two careful almanacs can therefore land on different dates without either being wrong. Where we place a festival, we show the rule we applied, so you can tell which question was answered.
Institutional research & support
Pūjāvāni is owned and developed by CHITRAM.AI PRIVATE LIMITED. The calculation surface is callable by a third party under a tenant-scoped credential, so a temple trust or an institution can use it, not only a browser.
How far this goes
- Pūjāvāni sends no reminders and no notifications. Nothing here will tell you that a fast has begun.
- Every vidhi here is a draft. The procedures were written in-house and none has yet been read by a practising purohit, so a page shows how a puja is done — not how it must be done, and not what your own sampradayam keeps.
- Vaasthu findings read classical rules against a plan you supply, and the jyotisha readings are given as the tradition computes them, not as predictions of fact. They are not structural, legal or planning advice, and nothing here replaces a qualified professional.
- Nothing here files, submits or lodges anything with any authority.
Values
Preservation of knowledge
This tradition was developed over millennia by Indian astronomers and mathematicians. Computing it faithfully is how it stays legible to the people who inherit it.
Meant to be heard
The day's reading, a sankalpam, a puja's mantra and a hymn's text can each be read aloud. This practice is recited at home, not read off a screen.
Education
Every figure is explained, and where a result depends on a choice of rule, the rule is shown.
Observational rigour
Nothing is looked up in a table. The answer changes when the place does, as it should.
Your birth details
A birth moment is often the only copy anyone holds. Yours is stored against your account and scoped to the organization you are signed in under; a request for a record outside your scope is answered as though it does not exist. Removing a chart retires it rather than erasing it, so a mis-click is recoverable. See the privacy policy for the whole of it.
