Muhurta implements classical Parāśari muhurta, following:
This is a defensible, mainstream, widely-used system. It is not the only one — and we're explicit about what we deliberately don't implement, because those are different schools, not omissions:
If you cross-check against a KP app, a tropical chart, or a regional almanac and see a different result, that's not a bug on either side — it's two internally consistent traditions.
Every day is described by five classical elements, computed from the real-time positions of the Sun and Moon for your location:
Tara bala (the Moon's relationship to your birth nakshatra) and chandra bala (the Moon's transit house from your natal Moon) build on this same daily Panchanga — each is scored as its own independent module, detailed below.
On top of the day's Panchanga, Muhurta reads your natal chart and blends in personal, chart-specific factors. Each is its own independent module — none of them override or gate another:
Your current Vimshottari daśā period (the multi-year, multi-month, multi-day planetary cycle you're running) is checked against the planet that classically rules the activity you're timing.
The natal strength of that same ruling planet — its sign dignity, house placement, retrograde status, and closeness to the Sun (combustion) — at the moment you were born.
Where today's transiting Moon falls in the nine-point tara cycle counted from your birth nakshatra — a classical measure of daily luck relative to your own chart, not a generic transit.
How many houses the transiting Moon has moved from your natal Moon — a separate, house-based reading of the Moon's current support.
The ruling planet's own current transit — its sign, nakshatra, and whether it's retrograde or combust right now.
The relationship between the ascendant rising right now at your location and the ruling planet's natal placement.
Whether today's transiting planets cast a classical Vedic whole-sign aspect onto the ruling planet's natal position — never a Western orb-based aspect.
The current planetary hour's ruling planet, read against both the activity's ruling planet and your active daśā lord.
Each activity type carries its own emphasis across these layers — timing a launch leans harder on Panchanga and Lagna Support; timing a strategic decision leans harder on Dasha Alignment and natal planetary strength. We don't publish the exact weighting per activity, but the principle is: different activities are governed by different planets, and the engine reflects that instead of scoring everything the same way.
Every day is split into 24 parts — but not regular clock hours. 12 happen between sunrise and sunset, and 12 happen between sunset and the next sunrise. Each part is called a hora. Because an hora is always exactly 1/12th of daylight or 1/12th of night, it isn't a fixed 60 minutes — it runs a little longer in summer and a little shorter in winter, tracking the actual length of the day at your location.
For every hora, the layers above combine into your score using the default weighting shown below — individual activities shift these weights, as described above, but this is the baseline:
Your Day Score — the single number shown at the top of your day — is simply the average of all 12 daytime hora scores.
All of the above combines into a single 0–100 score for any given hour, bucketed into three bands:
Conditions favor decisions, negotiations, launches, and anything that matters.
Moderate conditions — fine for steady work and planning, not the moment to force a peak decision.
Better suited to admin, research, and preparation than high-stakes calls.
The score reflects how well the timing factors align — it is not a guarantee of outcome, and a low-energy window is not "something bad happening." It tells you when conditions are working with you versus against you, so you can plan around it.
Alongside the score, Muhurta tracks the classical seven-part Choghadiya cycle across both day and night — each segment carrying a planetary lord and a favorable, neutral, or avoid quality. Day and night follow separate classical rotations rather than one rule repeated twice, which is also why, on certain nights, one segment's name can recur within the same night — a detail we've verified against traditional panchang references rather than assumed.
Muhurta also tracks the other named classical windows: Rahu Kaal, Yamaganda, Gulika Kaal, Abhijit Muhurta, Kaal Vela, Vaar Vela, and Kaal Ratri. Not all carry equal weight — Rahu Kaal and Yamaganda are hard exclusions from any recommended window. Gulika Kaal carries a more nuanced classical standing — favorable for recurring and saving actions rather than new beginnings — and is shown as such rather than as a flat block. Kaal Vela and Vaar Vela are informational only and do not enter scoring.
On the calendar itself, Rahu Kaal is overlaid by default, at every tier — no toggle required. Kaal Ratri is a nighttime window, so it only appears once you switch your calendar to show night hours (off by default); it's not hidden by design, it's simply inside the hours that aren't on screen yet.
How we recommend using this: don't just stare at the number. Look at your calendar first — your personal score already color-codes every hour, so scanning the week tells you where the good windows sit at a glance. Then, if you want a second opinion, layer the extra tools on top: turn on the Choghadiya overlay, or check whether that strong hour also avoids Rahu Kaal and Gulika Kaal. Overlays don't change your score — they're optional cross-checks. But when a strong personal score lines up with a favorable Choghadiya and a clear Rahu Kaal, that's the closest thing to a confirmed "yes" the system can give you.
Pick an activity and a horizon, and the engine scans the candidate hours ahead. It first applies hard exclusions — classically inauspicious windows and non-daylight hours by default — before any scoring happens. What remains is ranked using the same personalized composite described above, tuned to that activity's ruling planet. Windows that overlap an existing calendar event stay in the ranked list but are flagged as booked, rather than removed — so you can still see how a busy slot would have scored.
If natal or transit data needed for a slot is missing or incomplete, that slot is simply left out of the results rather than scored with a simplified fallback. We'd rather show you fewer windows than a misleading one.
The Vedic Companion is a chat assistant grounded in your actual natal chart and the same live data — today's panchanga, your current daśā, today's choghadiya, and current transits — that the rest of the app uses. It isn't a generic AI improvising astrology from a text prompt; it pulls your own calculated data on demand for every answer. For questions about a specific life domain — marriage, career, siblings, children, parents — it can also pull the relevant divisional chart (D9 Navamsha, D10 Dashamsha, and others) from your natal data, always read alongside your main chart rather than in isolation.
It's built to say "I don't have that" rather than invent a planetary position or the timing of a named window, and it frames everything as timing tendencies — not fixed prophecy or fatalistic prediction.
Your Circle lets you add the people who matter to you — a partner, a parent, a friend, a business partner — and see how your timing aligns with theirs, without asking them to create their own account.
The relationship read (we call it your Vedic Compatibility) draws on the same classical tradition as Ashtakuta / Guna Milan compatibility matching — the system referenced by sources like Drik Panchang — sourced from Prasna Marga (Harihara). We use a deliberately reduced, relationship-agnostic subset of it:
Like your personal score, the everyday Compatibility is bucketed into three plain-language bands — Strong alignment, Balanced, Some friction — never shown as a raw number or fraction. Each person's daily shared timing is computed fresh, the same way your own Day Score is, so the comparison stays real rather than a static label.
Marriage Match is an opt-in mode, available for a partner or love interest once a Compatibility Map has been generated. It runs the faithful classical calculation — not the softened subset above: all eight kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi), each carrying its traditional point weight toward the 36-point total, plus Mangal Dosha (Kuja Dosha) checked independently of the score.
The eight point tables and matrices behind this calculation are sourced primarily from Saravali (Maitreya) — an open, well-documented software implementation of the classical Ashtakoota system — cross-checked against Drik Panchang's own Ashtakuta references and other independent sources. Where two legitimate sources genuinely disagree on a specific value (a real, documented occurrence in a tradition this widely implemented), we say which one we followed rather than blending them silently.
