India's Official Calendar Reform
After Independence, India inherited 30+ regional calendars with no national standard. The Calendar Reform Committee (1952-1955), chaired by physicist Prof. Meghnad Saha (FRS), recommended a unified national Saka calendar. The Government of India adopted it on 22 March 1957, and the Positional Astronomy Centre (PAC) under the India Meteorological Department, Kolkata, has published the official Rashtriya Panchang annually since then.
The Rashtriya Panchang uses Drik Ganita (modern observational astronomy) with the Lahiri (Chitra-paksha) Ayanamsa — defined by Nirmal Chandra Lahiri's foundational ephemeris (founded 1939, government-adopted 1955). This is the reference for all Government of India offices, Gazette of India dates, AIR national broadcasts, and Doordarshan.
