Book of Indian Eras, with Tables for Calculating Indian Dates c2.27

c2.27

James Prinsep's Useful Tables are founded almost entirely on Warren's Kâla Sankâlita. But his tabular forms are much more handy than those of Warren, and his calendric scales for ascertaining corresponding dates by simple inspection are a really useful invention. For his own use he had wooden cylinders prepared round which the scales were pasted, so that the initial day of any Hindu or Muhammadan year could be set at once to its corresponding date in the Christian calendar. There are several misprints; but the only serious one is in the table of Hindu sidereal years, where the initial days of the Christian years on the left hand from A.D. 1753 onwards are continued in Old Style, while the initial days of the corresponding Hindu years are given in New Style right down to the end. Thus the present year A.D. 1882 is made to begin on Friday (which is O.S.), instead of on Sunday (N.S.), while Tuesday the 10th April is given as the beginning of the Hindu year in N.S.
