The Gang-Ngai Festival in Manipur is celebrated in one particular point of the year. The month of Wakching, which usually falls in the month of December or January of the English calendar, is when the Gang- Ngai festival is celebrated.

The Gang- Ngai festival is initiated with an Omen taking ceremony. The first day of the festival is meant for the honoring of ancestors. This ritual is considered to be very sacred by the Kabui Nagas. The last four days of the Gang- Ngai festival is completely dedicated to fun and celebration. The five days of the festival are marked by feasts, cultural performances and celebration. The Gang–Ngai festival is a part of the identity of the Kabui Nagas as it is through this religion that the Kabui Naga tribe of Manipur gets a chance of asserting their religion.
