Minjar Fair is celebrated every year in the month of Sawan.

Minjar Mela is celebrated in the Chamba valley of Himachal Pradesh, as a commemoration of the victory of the Raja of Chamba over the ruler of Trigarta (now known as Kangra), in 935 AD. It is said that on the return of their victorious king, people greeted him with sherfs of paddy and maize, as gift to symbolize prosperity and happiness. Minjar Mela is organized in August to thank God and ask His blessings for a good yield.
