@the-gravedigger saidThere are three timezones in Indonesia: western, central and eastern. Most of the population, by a long chalk, live in the western area: Java, Sumatra and a large chunk of Kalimantan.
The earth is an oblate sphere (flattened at the poles)
So 360 degrees around. There are 24 hours in a day. 360 divided by 24 = 15.
For every 15 deg. you travel east or west time changes by 1 hour. In practice countries modify this so small countries aren't on different time zones etc.
If you were to travel around the world in one direction you would be 24hrs out wh ...[text shortened]... to where you started. Except we have the International Date Line to correct this.
Hope this helps.
@fmf saidWhat are the 7 main time zones?
There are three timezones in Indonesia: western, central and eastern. Most of the population, by a long chalk, live in the western area: Java, Sumatra and a large chunk of Kalimantan.
From east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
I am assuming we have people who play on this site from all or most of these time Zones!
