How many international time zones does the earth have?

David + Allie

There are 24. Whatever time a.m. it is in your country, it will be exactly the same time p.m. in another country (which is 12 time zones ahead of or behind your country). If you travel from one country near one side of the International Date Line to another, although it may only take a few minutes, you can have lost or gained a day. Feb 05 01, 5:03 AM

The world is divided into 24 zones. However at any instant, there are 31 different local times in the world because several countries have zones which are not integer hours. Labrador, Canada is -3.5 GMT; Iraq is +3.5 GMT; Iran is +4.5 GMT; India is +5.5 GMT; Myanmar (Burma) is +6.5; Central Australia is +9.5 GMT and there are Chatham islands to east of New Zealand which are +12.75 GMT, the extreme east of Russia is +13 GMT. However I think there is no country with time zone for -11 GMT. * There is -11GMT time zone, so that makes 32 in all (not counting daylight saving time zones.) Feb 05 01, 9:36 AM
