In Zambia, the Shimunenga Ceremony of the Ba-Ila people of Maala in Namwala District is celebrated on the weekend of the full moon in September or October. Early in the morning of the first day, people gather at the shrine of Shimunenga, where traditional songs are chanted. There is also a cultural march past of women and girls in traditional attire, after which people are treated to performances by traditional dancers.
On the following morning, the drum is sounded and animals are taken to the river, where cattle is displayed in the traditional manner. The first cattle to cross the river will be those of the custodian of the shrine. This is followed by a demonstration of a mock lion hunt and pelican fishing. The occasion is marked with traditional songs in honour and praise of the Shimunenga ancestral spirits. Celebrations continue in the village with pit-stops for traditional beer at different places. The shimunenga ceremony takes place in the middle October and November.
