Synopsis A Compendium of Calendars is an encyclopaedic work on the topic of the Christian, Saka and Hijrah Calendars. It is very comprehensive and elaborate. It consists of mainly three parts, exclusively dealing with the Christian, Saka (Indian National) and Hijrah Calendars. The author is of the view that the extant books on the topic are not very comprehensive and analytical. Moreover, the method adopted is more problematical and time-taking too. For the sake of making it comparatively more informative, easy-to-use and time-saving, author thought it worthwhile to construct a completely new work to meet all the desiderata. This Compendium of Calendars has been prepared after considerable study and labour with the hope that it will be useful to the students and the scholars as well as the layman alike.
