Gawai Dayak

Gawai Dayak is a festival celebrated by Dayaks in Sarawak and West Kalimantan which is officially public holidays on 31 May and 1 June every year in Sarawak, Malaysia. It is both a religious and social occasion.
The word Gawai means a ritual or festival whereas Dayak is a collective name for the native ethnic groups of Sarawak and neighboring Indonesian Kalimantan who are the Iban also known previously as Sea Dayakand the Bidayuh people also known as Land Dayak and the Orang Ulu (inclusive of Kayans, Kenyahs, Lun Bawangs, etc.). Thus, Gawai Dayak literally means "Dayak Festival".
