Dhanurmas is a month in the Hindu calendar, Malayalam calendar and others. It corresponds to the zodiacal sign of Sagittarius, and overlaps with approximately the second half of December and about the first half of January in the Gregorian calendar. Worship of Lord Vishnu during the morning hours in Dhanurmasam is considered highly auspicious. Vishnu Sahasranama is chanted during the period. Other important mantras chanted are those dedicated to Goddess Lakshmi. There is a belief that worshiping Lord Vishnu on a single day during Dhanurmasam is equal to worshiping him for thousands of years.
