Kolkata Panchanga

Today's Tithi in Kolkata is Shashthi. Tithi is the lunar day — there are 30 per month, each governed by a presiding deity and suited to different types of action. Shashthi runs until the Moon travels another 12° from the Sun's position.

Rahu Kalam in Kolkata today is approximately 12:00 PM – 1:30 PM. Rahu Kalam shifts by weekday (Vara) and is always 1/8th of the day length. In Kolkata at 22.5726°N, the day length shifts with the season, so Rahu Kalam's actual start time varies by up to 20 minutes from the standard New Delhi reference.

Tithi, Nakshatra, Yoga and Vara are the same across India — they depend only on the Sun and Moon's positions. What changes by city is any window that depends on local sunrise: Rahu Kalam, Yamaganda, Gulika Kalam, Choghadiya, Abhijit Muhurta, and moonrise time. Kolkata is at 22.5726°N 88.3639°E, so its sunrise differs from New Delhi (28.6°N 77.2°E) by 45 minutes — and all sunrise-based windows shift accordingly.

Abhijit Muhurta is the most universally auspicious 48-minute window of the day, centred on solar noon in Kolkata. Because Kolkata is at 88.3639°E longitude, its solar noon falls at approximately 11.6:-23 IST (IST is set for 82.5°E). Abhijit is absent on Wednesdays in classical tradition.
