OLD IRANIAN CALENDARS

[In 1917, I made a study of the history of the Iranian system of time reckoning, with a view to writing an article on the subject in a Persian review. This took me at that time beyond the scope of the intended article, and the idea was ultimately dropped. I had, however, made a number of notes on that subject. Two years ago, I came across these notes, which again roused my interest in this question. I decided to carry out the original intention and, instead of throwing away these notes on which a considerable time had been spent, to incorporate them in a monograph on this somewhat complicated question. The work is already in the printer's hands, and will, I hope, be soon at the disposal of Persian scholars. I thought, however, it might be useful to give in English, as concisely as possible, the conclusion reached in the Persian work which amounts to some 350 pages, with some of the principal arguments supporting the opinion expressed therein.]
