The Astrolium Panchang calculator returns the complete five-limb Hindu calendar for any date, anywhere on Earth, in roughly 5 seconds. Tithi with paksha, nakshatra with pada (1 of 4), yoga, karana, vara, and the full daily timing breakdown — Abhijit Muhurta (48 minutes), Rahu Kalam (90 minutes), Yamaganda, Gulika, and all 8 Choghadiya periods. Computed on the Swiss Ephemeris with Lahiri ayanamsa (24.2°), the standard for Vedic work.
This is the free preview. For the deeper sidereal chart work, see the vedic birth chart calculator and the vedic astrology feature. For Saturn's slow-moving cycles affecting your moon, run the Sade Sati calculator.
What you get
The output runs in two layers. The five limbs themselves — what classical Jyotish calls pancha angas, the structural skeleton of the day. Then the timing breakdown, the part most people actually use day-to-day: which windows are auspicious for important work, which to avoid.
The five limbs explained
Tithi is the lunar day. There are 30 in a lunar month, split into the waxing fortnight (Shukla Paksha) and waning fortnight (Krishna Paksha). Each tithi runs longer or shorter than 24 hours because it is defined by the moon's angular separation from the sun, not by clock time. Tithi 1 (Pratipada) begins the moment the moon is 12° past the sun. Tithi 15 (Purnima or Amavasya) closes each fortnight.
Nakshatra is the lunar mansion — one of 27 fixed sectors of the sidereal zodiac, each 13° 20' wide. The moon transits one nakshatra roughly every 24 hours. Each nakshatra has a ruling planet (its dasha lord), a presiding deity, and a temperament. The pada is the quarter of the nakshatra (1 to 4) that locates the moon more precisely.
Yoga is the angular relationship of sun and moon, computed by adding their longitudes. There are 27 yogas, each carrying a name and a nature (auspicious, mixed, or inauspicious). Yogas like Vyaghata or Atiganda flag the day as obstructed; Siddhi or Sadhya mark the day as supportive.
Karana is a half-tithi. There are 11 karanas; 7 rotate through the month, 4 are fixed. The classification (movable, fixed, or destructive) tells you whether the half-day window favours dynamic activity, stable work, or rest.
Vara is the weekday and its ruling planet. Sunday-Sun, Monday-Moon, Tuesday-Mars, Wednesday-Mercury, Thursday-Jupiter, Friday-Venus, Saturday-Saturn. The vara's planet sets the broadest tone of the day; the other four limbs colour it in detail.
Auspicious and inauspicious windows
This is where most people actually consult the Panchang.
Abhijit Muhurta is the safest window of any day — roughly 48 minutes centred on local solar noon. Tradition treats it as overriding almost every other negative indicator. If you have to act and the rest of the day looks mixed, act inside Abhijit.
Rahu Kalam is a 90-minute window assigned to Rahu, the shadow node. It rotates by weekday: Monday morning early, Saturday at the third octave, and so on. Conventional advice avoids signing contracts, starting trips, or making large purchases during Rahu Kalam.
Yamaganda and Gulika Kalam are the other two daily inauspicious windows, also assigned by weekday. Treat them the same way as Rahu Kalam.
The Choghadiya layer divides the day into 8 roughly 90-minute periods labelled by nature: Amrit, Shubh, and Labh are good for any positive action; Char is neutral and supports travel; Rog, Kaal, and Udveg are best avoided for important work.
How Indians use Panchang daily
A typical morning glance at the Panchang answers three working questions: what tithi is today (which festivals or fasts apply), what nakshatra the moon is in (which activities the day naturally supports), and which windows to avoid. Whether you are picking a wedding muhurta or just deciding when to send a difficult email, the Panchang is the standard reference.
Astrolium's calculator presents all five limbs in clear cards with deity, nature, and end-time data, then the timing windows in a colour-coded grid. No login, no email — just the day's structure, ready to read.
