Authorities have identified 870 of the victims, while others still remain unaccounted for.
Archaeologists have been enlisted to help find the remains of massacred Israelis while search teams continue looking for bodies in open areas.
It comes as organisers of the festival vowed during a memorial ceremony that they would not let the tragedy keep them from "dancing again."
“We went through something that we had no control over, we will take care of everyone and help everyone,” said organisers Omri Sassi and Nimrod Arnin during the ceremony. Both lost loved ones during the massacre: Sassi lost four relatives and Arnin his sister.
“The Nova community suffered the largest number of murders. … This was the largest event we have done to date, a lot of people came from abroad to spend time at the event,” Sassi and Arnin told Walla News.
