In this festival teen-aged boys dressed up as cows, parade the streets of the town. This costume springs from the belief that cows help the members of the family who died within that year to travel to heaven smoothly. Some are also dressed up as an ascetic or a fool for achieving the same objective for their dead family members. Groups of mimics improvise short satirical enactment on the current social scenes of the town for the entertainment of the public. The week beginning from Janai Purnima actually unfolds a season of many good religious and cultural activities. All the Buddhist monasteries open their gates to the visitors to view their bronze sculptures and collection of painting for a week. At Patan, one observes the festival of Mataya at this time.

The festivity of Gai Jatra itself lasts for a week enlivened by the performance of dance and drama in the different localities of the town. The spirit of the old festival is being increasingly adapted by cultural centers, newspaper and magazines to fling humour and satire on the Nepalese Social and Political life.
