Bengal's regional almanac tradition: civil dates, tithi, nakshatra and Moon rashi with the calendar convention named.

Facts & conventions · calculation contract

One instant, with every assumption visible

The calculator samples 12:00 Bangladesh time in Dhaka. That is useful for exploring the quantities without claiming to reproduce a printed Panjika’s sunrise-to-sunrise event table.

Three calculations

Tithi: wrap the geocentric Moon longitude minus Sun longitude into 0–360°, then divide the circle into thirty 12° segments.

Nakshatra: subtract the named Lahiri ayanamsa from the Moon longitude, then divide the sidereal circle into twenty-seven 13⅓° sectors.

Moon rashi: use that same Lahiri longitude in twelve 30° sectors. The shared longitude is why this result links to the Vedic Rashi page.

What remains for a full daily Panjika

A full almanac needs sunrise for a named location, exact transition times, yoga, karana, observance rules and a selected regional authority. No “do this” or “avoid that” advice is inferred from the snapshot. Inspect a snapshot →

Bodhastra documents what astrological traditions have said, and when they started saying it. It is presented as cultural history and entertainment. Nothing here is medical, psychological, financial or predictive advice, and nothing here is a claim about what will happen to you.
