GMT and BST are two time zones that are used in different parts of the world. GMT is Greenwich Mean Time, which is the time zone used in the United Kingdom. BST is British Summer Time, which is the time zone used in most of Europe. The difference between GMT and BST is one hour. This means that when it is 12:00 noon GMT, it is 1:00pm BST.
What is GMT?
- GMT is short for Greenwich Mean Time. GMT is the mean solar time at the Royal Observatory in Greenwich, London. GMT was originally used as the international civil time standard, now it is mainly used as a time zone. GMT is also sometimes referred to as UTC or Coordinated Universal Time. GMT is a 24-hour timekeeping system. GMT does not change with daylight saving time.
- GMT is calculated by measuring the mean solar time at the Greenwich meridian, which passes through the Royal Observatory in Greenwich, London. GMT has been replaced as the international civil time standard by Coordinated Universal Time (UTC).
- However, GMT is still commonly used as a time zone. UTC is a 24-hour timekeeping system that does not change with daylight saving time.UTC is based on Atomic clocks and GPS satellites. The main difference between GMT and UTC is that GMT does not change with daylight saving time while UTC does.
What is BST?
BST, or British Summer Time, is the time zone used in the United Kingdom during the summer months. BST begins on the last Sunday in March, when clocks are moved forward one hour, and ends on the last Sunday in October, when clocks are moved back one hour. BST is one hour ahead of Greenwich Mean Time (GMT), which is the time zone used in the UK during the winter months.
BST is also used in some other countries, including Ireland, Portugal, and parts of Australia. BST is sometimes referred to as “Daylight Saving Time” because it allows for more daylight hours during the summer months. BST begins at 1:00am GMT on the last Sunday in March and ends at 1:00am GMT on the last Sunday in October. During BST, clocks in the UK are moved forward one hour. As a result, BST is five hours ahead of Eastern Standard Time (EST) in the United States. BST is four hours ahead of Central European Time (CET). BST is also known as “Greenwich Mean Time+1” (GMT+1).
Difference between GMT and BST
GMT and BST are both time zone acronyms that are used to describe the time in different parts of the world. GMT stands for Greenwich Mean Time and is based on the mean solar time at the Royal Observatory in Greenwich, London.
- BST stands for British Summer Time and is GMT+1 hour ahead. BST is observed in the United Kingdom from March to October. GMT is used all year round in the UK. During daylight savings time, GMT is GMT+1 hour ahead of BST.
- In other words, when it is noon GMT, it is 1pm BST. When it is noon BST, it is 1pm GMT. GMT and BST are both acronyms for different time zones that are used to describe the time in different parts of the world.
- GMT is used all year round in the UK while BST is only used during daylight savings time. GMT is Greenwich Mean Time while BST stands for British Summer Time. GMT is based on the mean solar time at the Royal Observatory in Greenwich, London while BST is GMT+1 hour ahead.
When it daylight savings time, GMT is 1 hour ahead of BST. In other words, when it noon GMT, it 1pm British Summer Time. Noon British Summer Time would then be 1pm Greenwich Mean Time.
Conclusion
The Greenwich Mean Time (GMT) is the time zone that is used in the United Kingdom and other European countries. During Daylight Saving Time (DST), which usually occurs from late March to early October, clocks are moved forward one hour so that people can enjoy more daylight hours. This means that the GMT time zone becomes British Summer Time (BST). If you are traveling in Europe during DST, be sure to remember to change your watch or clock accordingly!
