The timezone CST in Macao

Only 1 nationwide time zone

Standard time:	UTC +8	China Standard Time (CST)
Daylight saving time:	UTC +9	discontinued 1979

Macao has an east-west extension of 0.02 degrees of longitude. Given the country's location in East Asia, this corresponds to about 2 kilometers. With such a small extent the course of the sun at different positions in the country hardly matters. The position of the sun in the west of the country deviates from that in the east only about 5 seconds. This means the sun rises and sets 5 seconds later in the west than in the east.


The China Standard Time also applies in parts of China and in Taiwan.

No more daylight saving time in Macao

Due to the sun's orbit around the equator, the days are longer in summer (June to September in the northern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to the relative proximity to the equator, the impact in Macao is not particularly large. Concelho de Macau is only 2,450 km from the equator. A day in midsummer would then not last from 05:41 to 19:13, but from 06:41 to 20:13. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, in 1979, the decision was made to finally abandon daylight saving time in Macao.
