In a statement issued Wednesday on behalf of Gibb's family, his relatives confirmed that a service for "close family and friends" would take place on June 8.
No details about the location of the funeral have been disclosed.
The Gibb family requested that mourners offer donations, rather than flowers, to two children's charities on the Isle of Man, where Gibb was born.
Gibb, a founder of the Bee Gees with his two late brothers, died on May 20 after a long battle with cancer at the age of 62.
Plans have not yet been confirmed for a planned public memorial service.
