This is the standard time of the Eastern US, Canada and parts of the Caribbean. It is in most places observed only in the winter months, from November to March. The origin of EST is the same as for most time zones – it was introduced when the railroad was built across the United States. It is important to note that there is also Eastern Standard Time in Australia, but this is usually called AEST and thus not to be confused with EST.
Most of the Eastern seaboard of the US observe EST, as well as most locations in Eastern Canada although there are a few exceptions. Locations such as New York, Washington, Quebec and Ontario are all on Eastern Standard Time. Also some Caribbean locations such as Jamaica, Haiti and Panama are in this time zone.
It is important to note that with the exception of Panama, Jamaica and a couple of locations in Canada and the US most in this time zone do observe DST and thus switch to EDT in the summer. As always, it is better to look up the actual location than the timezone itself.
Korean Standard Time, or KST for short, is the standard time zone for South Korea. It is 9 hours ahead of UTC. North Korea was on KST until 2015 when they introduced their own Pyongyang Standard Time, which is 30 minutes behind Korean Standard Time.
South Korea is the only country using Korean Standard Time. It is however the same time as JST – Japan Standard Time and AWDT – Australian Western Daylight Time (i.e. when Western Australia applies Daylight Saving Time). As noted above, North Korea are since 2015 using their own time zone.
All cities in Korea applies KST, including Seoul, Busan, Incheon, Daegu, Daejeon, Suwon and Gwangju.
DST (Daylight Saving Time) is currently not applied in South Korea, although there were experiments during the 1988 Olympics.
