Olgia is celebrated on the first day of Bhado (middle of August), when the harvest is lush and green, vegetables are in abundance and the milch animals very productive. In ancient times sons-in-law and nephews would give presents to fathers-in-law and maternal uncles, respectively, in order to celebrate Olgia.

Today agriculturists and artisans give presents to the owners of their land and purchasers of their tools and receive gifts and money in return. Binai (oral harp), datkhocha (metallic tooth pick), metal calipers, axes, ghee, vegetables and firewood are some of the presents exchanged on this day. People put ghee on their foreheads and eat ghee and chapatis stuffed with 'urad' dal. It is believed that walnuts sweeten after this festival. This festival, which is a celebration of the produce of the land, is now seldom celebrated.
