As of July 20, 2021, as Singapore returns to phase 2, the limit on group sizes for social gatherings will go back down to 2 people. It was increased to 5 people last June, but as the island battles another surge, the limit is reduced once again   It will take effect starting on July 22 until August 18. If the restrictions are relaxed after August 18, residents may be able to host birthday parties again.
