France therefore has more time zones than any other country in the world, even though the main part of France in Europe only uses one time zone. With its overseas territories, France uses 12 different time zones, although even 13 if we take into account France’s territorial claims in Antarctica. Many time zones have also postcolonial European countries which have their overseas territories around the world, such as: France, the UK or Denmark.Īs a curiosity, I would like to add that France has the most time zones. These include: Russia, Canada, Brazil, Australia, Indonesia, USA Mexico and a few more. Many time zones have huge countries so those which are cut by more than one meridian. That’s why we have 24 hours in a day and 24 main time zones as shown on the map below. Apart from that there is 360 degrees in a circle and that’s why there is also 360 degrees around the planet. Time zones also correspond to our biological nature because we are diurnal animals and they depend on the rotation of the Earth which the total turn around takes 24 hours. We invented time zones to make a better use of time in economic terms, because if the entire planet was on the same time the world would not be able to produce enough energy, hence the DST (Daylight Saving Time). Whether it’s a day or a night depends on the rotation of the Earth in the sense of a particular position of the given part of the Earth towards the sun. Time was invented by people so it is easier to identify it. Nevertheless, time zones were invented in 1879 by a Scottish born Canadian Sir Sanford Fleming. Please note the colours on the map and its explanation underneath which show the time differences as we move west or east from Greenwich and note that the standard time zones move by full hours GMT+ and GMT. When travellers are on the other side of the world they are not sure about the actual time difference and whether it’s the right time to call home and not to wake up parents in the middle of the night. That’s why I’ve attached the map showing time zones of the world. As time “0” I have shown the Greenwich Mean Time ( GMT) where the world famous Observatory was founded in 1675 by Charles II. Whilst flying around the world I’ve noticed that people rarely know what time it will be when they get to their destination. We invented time zones to make a better use of time in economic terms, and because time zones correspond to our biological nature.
