These days, there is an upswell of interest in Indian mathematics, Indian astronomy and Indian religions, observances and festivals. Most of these observances and festivals are celebrated on particular dates of one calendar or the other. For example, the birthday of Lord Rama, one of the most important deities of veneration among Indians, is celebrated on the ninth day of the bright half of the month of Chaitra. What does that mean?
In India, while we follow the western (Gregorian Calendar) for civil and official purposes, at home, for religious and liturgical purposes we follow a myriad of calendars based on the region we are in, based on our religion, our community etc.. This gives rise to many questions that an average person is faced with.
I am in the process of writing a new book on the subject of calendars of India. This book is in the workshop. I am right now gathering materials for this book. Am looking at six to nine months for the completion of the book. Then another year for publishing it?
