Singapore time difference and China time.

There is no time difference between Singapore and China.

Theoretically, both Singapore and China belong to East Zone 8. Singapore is located in UTC+7 time zone, and UTC+7 was officially used on May 3 1905. Before that, the time in Singapore was UTC+6: 55: 25.

During the Japanese occupation of Singapore, Singapore nominally adopted daylight saving time all year round, which actually made Singapore time consistent with Japanese time, that is, UTC+9. Restore the original daylight saving time after the war, UTC+7: 30 = Hong Kong time -30 minutes.

198 1 year, as neighboring Malaysia changed the standard time from UTC+7: 30 to UTC+8, it was convenient for Singapore to change it to UTC+8 after 1982 and 1.

Time zone division method:

The earth where human beings live is round. Besides revolving around the sun, it also rotates from west to east. People living in the east see the sun earlier than those living in the west, which brings a lot of trouble to the timing in different regions.

For the convenience of timing, 1884 International Meridian Conference held in Washington, USA clearly divided the world into 24 time zones, namely 12 in the east and 12 in the west. At the same time, it is stipulated that the former site of Greenwich Observatory (UK) is used as the middle time zone, also known as the zero-time zone. Each time zone spans 15 degrees, and the difference between the two time zones is 65.

There are 12 time zones in the east and west. The number in the eastern time zone is positive, and the number in the western time zone is negative. The formula for calculating the time zone can be applied: calculated time zone = known time zone-(time zone of known time zone-time zone of the area to be calculated).
