"It would have been possible if the two clubs had reached such an agreement but they haven't and the tight schedule leaves no room for a postponement," Serbian league commissioner Branislav Delic told Reuters by telephone on Friday.
"The match will go ahead as planned on Saturday April 23 because last-minute changes to the competition schedule, which was drawn up last July, are not possible" he said.
"The date is not an official religious holiday and hence organising the derby as planned should not offend anyone's religious beliefs."
With the fixture sandwiched between Easter Friday and Sunday, the Serbian Orthodox Church issued a statement earlier on Friday saying no football should be played on a day its "faithful children spend in prayers and tranquility."
"As far as we are concerned, the match will go ahead when it's supposed to and we are looking forward to it," Partizan's secretary general Darko Grubor said.
"We are the hosts and therefore in charge of organising the match, so it would be rather awkward to shift the entire event at what would be an unfeasibly short notice."
"I don't know what each individual player thinks about the issue, but winning the league is certainly the first thing on their minds and I am sure that none of them will see playing on April 23 as an act of sacrilege," he said.
"We are preparing for the two upcoming games against Metalac Gornji Milanovac and Sloboda Point Sevojno, where we need to take maximum points to stay in the hunt."
