The closing ceremony will now be held on August 30, instead of August 31 which is the eve of the key holiday for Muslim.
Just months before the start of the biennial event in August, authorities announced the closing ceremony in Muslim-majority Malaysia will be a day earlier than scheduled, due to the clash with Islamic festival Hari Raya Haji.
The celebration will now be held on August 30, instead of August 31 which is the eve of the key holiday for Muslims, Sports Minister Khairy Jamaluddin said.
Khairy told reporters on Tuesday that the change of date would not be an issue for the games which begin on August 19.
"The closing date of the SEA Games has been brought forward by one day, from August 31 to August 30. This is for us to celebrate a (Muslim) religious event ... which falls on August 31," the minister said.
"But this will not create any big problems to the competition in terms of venue or accommodation because we had created a buffer period from the start of the competition."
Khairy added there will be some changes made to the schedule of a few sports events but that "by August 30th we would have finished all the events".
The previous SEA Games unfolded in Singapore, which produced a slickly-organised event based around their newly-built, billion-dollar Sports Hub complex.
However, there were several controversies at the Games including arrests for alleged football match-fixing, and the Philippines' request for a gender test on an Indonesian women's volleyball player.
