Summer Time

Due to daylight being longer in summer, the clocks in Macao are put forward one hour to save and make full use of the daylight. Contrary, the clocks are put backward one hour in winter as the daylight is shorter. The method to define the legal time is called “Summer Time”. According to the historical information, whenever summer time was being implemented, the government of Macao at that time would notify the public through public notices.
