Vishuddha Siddhanta Panjika
Hindu astrological almanac

Vishuddha Siddhanta Panjika (Bengali: বিশুদ্ধ সিদ্ধান্ত পঞ্জিকা) is a panjika (almanac) that was first published in 1297 Bengali year (1890 AD). Madhab Chandra Chattopadhyay of the Bengal of undivided India was the first editor.
Accuracy
The 19th century Bengali almanacs that gave details of tithi, nakshatra, etc. were generally not in conformity with the position of planets. A true panjika has to tally with the scientific observation. To meet this end, prominent astrologers of that time — almanac reformist of Orissa Mahamahopadhyay Chandrashekhar Sinha Samanta, Lokmanya Bal Gangadhar Tilak of Pune, Western India, scriptural scholars like Bapudeva Sastri and Ketkar, experts from Kashi like Madan Mohan Malaviya, Mahesh Chandra Nyayratna Bhattacharyya, Sasadhar Tarkachudamani, Acharya Yogesh Chandra Roy Vidyanidhi of Bengal — advised the publication of Vishuddha Siddhanta Almanac.
Approval and adoption
Vishuddha Siddhanta Almanac is recognized by scholars of scriptures such as Deshikottama Dr Srijiv Nyayaratna, mathematics scholar Nirmal Chandra Lahiri, internationally known scientist Prof Megh Nad Saha, et al.
This almanac is approved and followed by Kanchi matha, worldwide Ramakrishna Math and Ramakrishna Mission, Satsanga Ashrama of Deoghar and other religious organisations.
Rashtriya panchang
The calculations of the almanac are fully done with the help of computers to show the accuracy of the renderings and, therefore, the timing of the puja and parvan for occasions are free from any mistake. Hence the Indian national calendar (Rashtriya Panchang) published by the Government of India fully tallies with the almanac.

Why this record matters
The subject matters to the general reference register because the source frames it as hindu astrological almanac. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 18, 2026. The linked authority identifier is Q17031570. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1297 and 1890.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
