Sithinakha

Sithinakha

May-June; sixth day of waxing half of Hindu month of Jyestha
This is the birthday of the Hindu god Kumara, also known as Skanda, the god of war and son of Shiva. Kumara has six heads because he was nursed by the karttikas—six women who, as stars, comprise the Pleiades. For this reason he is also called Karttikeya, "son of Karttikas." The six heads also represent the six senses (including extrasensory perception). He has a large following under the name Subrahmanya, meaning "dear to the Brahmanas."
Most Hindus observe this day with a ritual purification bath followed by processions to the temples to honor Kumara. It is also considered a good opportunity to clean out wells and tanks, because the snake gods are off worshipping on this day and it's safe to enter their habitats.
In Nepal, eight different kinds of cakes, made from eight different grains, are offered to Kumara on his birthday, and for this reason Sithinakha is sometimes referred to as the Cake Festival . Lotus-shaped windmills are often set on rooftops at this time, to symbolize the end of bad times and the onset of holier days.
