Sithi Nakha in Kathmandu Valley
Sithi Nakha is a Newar festival held on the sixth day of the bright fortnight of Jestha, marking the start of the monsoon farming season and honoring Kumar, the son of Shiva and Parvati also known as Kartikeya. Communities traditionally use the day for cleaning wells, ponds and stone water spouts ahead of the rains.
The Kathmandu Valley's traditional water supply, long before piped municipal systems, depended on an intricate network of wells, ponds and carved stone spouts called hiti, fed by ancient canals and aquifers that Newar engineers developed over centuries.
