Kartik is the eighth month in the Hindu lunar calendar, typically falling between October and November in the Gregorian calendar. It is considered an auspicious time for various religious activities and festivals, including the celebration of Diwali, the festival of lights, which usually occurs in this month. During Kartik, many devotees engage in rituals and prayers, especially to Lord Vishnu and Goddess Lakshmi. The month is also associated with the Kartik Purnima festival, which marks the full moon day and is significant for spiritual observances and pilgrimages to sacred rivers and temples.
