Catering establishments and night-clubs, discotheques or other premises where dancing is held, may remain open until 4am on Christmas Eve and New Year's Eve, the Ministry of Finance said.
"All obligations concerning the playing of amplified music remain unchanged and no annoyance or inconvenience to neighbours is permitted by any sound which may be heard from outside the premises or by anything else done inside or outside the premises," the ministry said.
It warned of police action if such conditions were not observed.
