The author checked the dates of more than 250 inscriptions from Burma, Thailand, Cambodia, and Laos with a high degree of accuracy and reproduced old calendrists' calculations in an established calendar for each year from A. D. 638 to 2000. The introduction provides an outline of the calendrical system and some explanation of its technical aspects. This work is of extreme usefulness to all scholars of Southeast Asia when verifying or discounting calendrical and astronomical records in royal and monastic inscriptions, as well as when resolving ambiguities and correcting misreadings.
