When the sky is touched in a blink of an eye, when communication with any part of the world is just waiting for a signal, the calendar is welcomed in the inner circle of the Bengali household. Is this just backwardness ? or is it due to the multi-faceted function of the calendar. In this book, the author Panjikar sheds light on many important aspects of this unknown, neglected public life. Analyzing the calendar of two hundred years, he brought forward the auspicious, inauspicious time or religious instructions as well as religious neutrality and science-minded instructions. This apparent contradiction is the crux of the calendar.
