Karthigai Deepam is a popular festival celebrated by Hindus, particularly in Southern India. It is also known as the Festival of Lights and is dedicated to Lord Murugan, the Hindu god of war. The festival falls on the full moon day of the Tamil month of Karthigai.

During Karthigai Deepam, houses and temples are adorned with earthen lamps to symbolize the victory of light over darkness. Special prayers and rituals are performed to invoke blessings for health, wealth, and prosperity. The lighting of the lamp is believed to ward off evil and bring peace and happiness to the home.

In addition to the religious significance, Karthigai Deepam is also a time for families to come together and celebrate with feasts and gatherings. Traditional sweets and savories are prepared and shared with loved ones. The festival culminates in a grand display of fireworks and bonfires in the evening to mark the end of the festivities. It is a time of joy, togetherness, and spiritual renewal.
