Highlights
One Nation, One Panchang Portal
Central Sanskrit University, Lucknow is building a digital portal to provide verified astronomical data to almanac makers, reducing confusion in festival dates across India.
550-Year-Old Calculation Method Refined
The university studied and refined Acharya Ranganath's Beejakarma-Sanskara method from about 550 years ago to achieve more accurate planetary positions.
Preserving Traditions, Not Abolishing Them
The initiative aims to coordinate verified calculations across Purnimanta and Amanta traditions, not to impose a single method or eliminate any panchang tradition.
Background
India has multiple panchang (almanac) traditions based on different rishi paramparas, calculation methods, and planetary tables. This leads to variations in festival dates, planetary positions, and sunrise-sunset times for the same location, causing confusion. Central Sanskrit University, Lucknow has been researching since 2022 to address this.
Key Analysis and Impact
The portal will provide verified celestial data (tithi, nakshatra, yoga, karan, planetary motion, sunrise-sunset) to registered almanac makers free of cost every year. The research refined the 550-year-old Beejakarma-Sanskara method of Acharya Ranganath. The Suryasiddhanta's traditional calculation method has also been tested against modern astronomical observations. The findings may be included in the next authentic edition of Suryasiddhanta.
Way Forward
An annual national Pandit Parishad or Vidwat Sammelan will be organized to discuss udayatithi and festival date determination. This will bring together astrologers, almanac makers, and dharmashastra experts. The initiative preserves the diversity of panchang traditions (Purnimanta, Amanta) while standardizing the underlying verified astronomical data.

How exams will ask this
- Data: 20 months of free celestial data for almanac makers
Don't make this mistake!
The initiative is NOT merging all panchangs into one; it preserves multiple traditions while providing a common verified astronomical database. Do not confuse 'One Nation, One Panchang' with abolishing regional panchang diversity.

Stuck? Get it in one tap
Different panchangs (Hindu almanacs) in India often show different dates for the same festival because they use different calculation methods. Central Sanskrit University, Lucknow is building a website where almanac makers can download verified astronomical data for 20 months for free. This will help reduce confusion while keeping regional traditions alive.
