Samvat
सम्वत् पंचांग
Hindu calendar guide
पंचांग
The five-limbed Hindu almanac that turns astronomy into daily guidance.
Panchang joins tithi, nakshatra, yoga, karana, and vara with local sunrise to explain which Hindu date and qualities are active for a place and moment.
A Panchang is not a generic calendar page. It is a location-sensitive astronomical reading of the day.
The five limbs describe lunar phase, Moon position, Sun-Moon relationship, half-tithi division, and weekday.
Festival and vrata dates depend on which Panchang condition prevails at a rule-specific moment such as sunrise, pradosha, madhyahna, or nishita.
Tithi measures the Moon-Sun separation in 12 degree steps. Nakshatra measures the Moon position among 27 lunar mansions. Yoga measures the combined longitudes of the Sun and Moon. Karana is half of a tithi. Vara is the weekday, tied to the classical planetary sequence.
Together these five limbs give a layered description of time. A civil date only says that it is Tuesday, 14 July. A Panchang says what the Moon is doing, where it is moving, what lunar day is active, and which observance rules apply.
Many Hindu dates are assigned by the tithi or nakshatra present at local sunrise. This is why the same lunar condition can produce different civil dates in Delhi, London, New York, or Sydney.
A Panchang therefore starts with place: latitude, longitude, timezone, sunrise, sunset, and sometimes moonrise. The calendar is traditional, but the workflow is computational.
First read the tithi and paksha, because many observances begin there. Then read the nakshatra, yoga, karana, sunrise, sunset, moonrise, and any special day windows such as Rahu Kaal or Abhijit Muhurat.
For planning, do not stop at the name of the day. Check whether the relevant tithi ends before the ritual moment. A tithi active at sunrise may end before evening, and an evening puja may require a different rule.
A Panchang page looks simple, but it is built from a precise sequence of astronomical steps.
This is why Samvat shows both the date and the reason behind it. The explanation is part of the calculation, not decoration.
Use these as working patterns when reading Panchang details or planning around Hindu dates.
You want to know whether tomorrow is the fasting day in your city.
The correct date comes from the sunrise tithi and follow-up timing, not from a fixed Gregorian date.
A festival appears one day earlier in one country than another.
The difference is often the expected result of the same rule applied to different skies.
Panchang preserves a way of treating time as observed nature, not just numbered boxes. It connects the day to sunrise, the Moon, the Sun, and recurring celestial cycles.
The remarkable part is not only that the system is old. It is that its rules are mathematical enough to be computed today, city by city, while still serving daily spiritual and cultural life.
