A Panchangam is used for Astrological and Religious purposes. Panchangam is the ancient Indian astrological guide. This Panchangam covers different aspects of astrology like phase of the moon, position of stars and planets etc... The basic purpose of panchangam is to determine the Hindu Religious Festivals and auspicious times.

The traditional Panchang books and Patra Books were quite sophisticated for common man and thus Lala Ramswarup Panchang was invented and introduced as a simplified Panchang, one which common-man could use. It was first of its kind. Lala Ramswaroop Ramnarayan Panchang Calendar is considered as the most authentic & accurate panchang calendar.
