History of the Calendar in Different Countries Through the Ages M.N. Saha and N.C. Lahiri COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH Rafi Marg, New Delhi- 1 10001 1992 Part C of Report of Calendar Reform Committee, Government of India First published: 1955 Reprinted: 1992 © Council of Scientific & Industrial Research, New Delhi Printed by Publications & Information Directorate Dr K.S. Krishnan Marg, New Delhi -110012 FOREWORD The Council of Scientific & Industrial Research (CSIR) of the Government of India appointed a Calendar Reform Committee under the chairmanship of Prof. Meghnad Saha in November 1952. The Committee was entrusted with the task of 'examining all the existing calendars which are being followed in the country at present and after a scientific study of the subject, submit proposals for an accurate and uniform calendar for the whole of India'. The following were the members of the Committee: Prof. M.N. Saha, D.Sc, RR.S., M.P. (Chairman) Prof. A.C. Banerji, Vice-Chancellor, Allahabad University Dr. K.L. Daftari, Nagpur Shri J.S. Karandikar, Ex-Editor, The Kesari, Poona Dr. Gorakh Prasad, D.Sc., Allahabad University Prof. R.V. Vaidya, Madhav College, Ujjain Shri N.C. Lahiri, Calcutta (Secretary) Dr. Gorakh Prasad and Shri N.C. Lahiri came in place of Prof. S.N. Bose and Dr. Akbar Ali who were originally appointed but were unable to serve. The Committee's Report was submitted to CSIR in 1955 and the Government, in accepting the recom- mendations of the Committee, decided that 'a unified National Calendar' (the Saka Calendar) be adopted for use with effect from 21 March 1956 A.D., i.e., 1 Chaitra 1878 Saka. The Report of the Calendar Reform Committee was published by CSIR in 1955. Part C of the Report consisting of a review of 'History of the calendar in different countries through the ages' by Prof. M.N. Saha and Shri N.C. Lahiri was also published separately. This useful publication has been out of print for some time and scientists in general, and astronomers in particular, have been conscious of the non-availability of this valuable review. Therefore, the CSIR has decided to reprint it. No changes have been made from the original except that 'Corrigenda and Addenda' have been incorporated into the text, and consequently the bibliography and the index (which pertain to the whole report) have been repaginated. The title page of the Report, Jawaharlal Nehru's message, and Saha & Lahiri 's preface have also been included in the present volume. I hope that this reprinted volume will be found useful and informative by calendaric astronomers, science historians and scientists in general. S.K. Joshi New Delhi Director-General 15 August 1992. Council of Scientific & Industrial Research and Secretary, Department of Scientific & Industrial Research FACSIMILE OF ORIGINAL COVER REPORT OF THE CALENDAR REFORM COMMITTEE GOVERNMENT OF INDIA Council of Scientific and Industrial Research, Old Mill Road, New Delhi. 1955 MESSAGE I am glad that the Calendar Reform Committee has started its labours. The Government of India has entrusted to it the work of examining the different calendars followed in this country and to submit proposals to the Government for an accurate and uniform calendar based on a scientific study for the t^hole of India. I am told that we have at present thirty different calendars, differing from each other in various ways, including the methods of time reckoning. These calendars are the natural result of our past political and cultural history and partly represent past political* divisions in the country. Now that we have attained independence, it is obviously desirable that there should be a certain uniformity in the calendar for our civic, social and other purposes and that this should be based on a scisntific approach to this problem. It is true that for governmental and many other public purposes we follow the Gregorian calendar, which is used in the greater part of the world. The mere fact that it is largely used, makes it important. It has many virtues, but even this has certain defects which make it unsatisfactory for universal use. It is always difficult to change a calendar to which people are used, because it affects social practices. But the attempt has to be made even though it may not be as complete as desired. In any event, the present confusion in our own calendars in India ought to be removed. I hope that our Scientists will give a lead in this matter. New Delhi, February 18, 1953.
