They are the widest near the equator and zero at the North and South poles. The imaginary beginning of the time zone map is in Greenwich, a suburb in London that sits atop longitude zero.
But why is this important? Having 24 different time zones on Earth means that wherever in the world you are, noon is the middle of the day when the sun is the highest while midnight is the middle of the night. However, those times will not occur simultaneously in all parts of the world. Just as the sun is setting in London, it will be rising over your friends in Auckland. How come? In addition to different time zones and different time offsets around the globe, exact time also depends on whether the particular country or region observes the daylight saving time or not.
Daylight saving time is a system used to make use of the daylight hours during the summer months: in countries that observe the DST, clocks are moved forward in spring usually by one hour so that people can enjoy more hours of sunlight. In the fall, the clocks are moved back an hour to account for shorter days. Daylight saving time was first introduced in wartime Germany in an effort to save energy, and its use quickly spread around the world.
Currently, over 70 countries around the world observe daylight saving time changes, although not everybody is happy about it: Europeans and Americans in particular wish the DST to be abolished, as recent surveys suggest.
Once again, to avoid confusion, the time zone converter tool is the simplest solution: it automatically adjusts for DST differences and gives you an instant result.
Knowing your time zones is essential if you work or communicate with people around the world — but it can also be fun. For example, you can use a time zone converter tool to find out just how many birthdays you can have: because of the time zone differences, you can celebrate your birthday with a breakfast in Paris, then fly to New York to have a birthday brunch, and then head to Hawaii for a birthday party.
