Karthigai Deepam is a significant festival celebrated in the southern Indian state of Tamil Nadu and by the Tamil diaspora around the world. It is also known as Karthikai Deepam. The festival is observed on the day of the full moon in the Tamil month of Karthigai, which usually falls in November or December. There are specific types of lamps made in the name of Karthigai Deepam to celebrate Lord Kathikeya/ Lord Muruga's birth. Several bronze lamps are lit around the front yard of houses to dispel darkness on this day. It is also believed that ancestores or "Pithrus" take advantage of this light to make their way back to their abode after "Mahalaya paksham" a solemn period of offering water and sesame seeds to the departed for a whole 15 days, before which they descend.
