Janai Purnima also known as the sacred thread festival is being observed across the country on Thursday.

On the occasion, Hindu Brahmins and Chhetris who have undergone Bratabandha (hair shaving ceremony) change the sacred thread (janai) and also tie sacred thread around the wrist of the right hand.

It is also believed that this thread should be removed only on the day of Laxmi Puja that falls during Laxmi Puja in Tihar.

Janai Purnima is also popularly known as Rakshya Bandan.

On this day, sisters offer rakhi (a symbol of protection) to their brothers.

Meanwhile, Gaijatra or the cow festival is also being observed in the Kathmandu Valley.

On the occasion, living kin paid homage to those who had passed away in the past one year.
