The Bisuddha Siddhanta Panjika is one of the most respected and scientifically accurate almanacs used by Bengali Hindus to determine auspicious dates, religious festivals, and planetary positions. Unlike traditional panjikas, which often rely on outdated astronomical calculations, Bisuddha Siddhanta Panjika follows modern scientific principles, making it a reliable guide for astrological and religious purposes.

The Need for a More Accurate Panjika

Before the introduction of Bisuddha Siddhanta Panjika, most Bengali almanacs followed Surya Siddhanta, an ancient Hindu astronomical text. However, over time, the calculations in Surya Siddhanta became slightly inaccurate due to the natural movement of celestial bodies. These errors led to inconsistencies in festival dates and planetary alignments.

To address this issue, this Panjika was introduced, using updated astronomical methods to correct these errors. It is based on the calculations of Siddhanta Jyotish (scientific astronomy) rather than traditional practices, ensuring precision in marking ekadashi, sankranti, amavasya, purnima, and other important tithis (lunar phases).

Who Created Bisuddha Siddhanta Panjika?

The Bisuddha Siddhanta Panjika was first published in 1890 by Bangiya Panjika O Patrika, following the calculations of renowned Bengali astronomers like Babu Mahananda Haldar and Siddhanta Bagish. They aimed to remove errors from the existing almanacs and create a scientifically accurate panjika for the Bengali community.
