World time zones by country

All the observed world time zones are listed by country or territory in the table below. There are the independent states with multiple time zones, the record-holder is France with 12 zones, but 11 of them are used in overseas areas and only one in the country's mainland. The same situation is in the United Kingdom, Denmark, New Zealand, Netherlands. The countries with multiple time zones in the mainland area (some of them also have the insular territories) are Russia, USA, Canada, Australia, Mexico, Brazil, Indonesia, Kazakhstan, Mongolia, Democratic Republic of the Congo, Kiribati, Micronesia, Chile, Spain, Portugal and Ecuador.

The Daylight Saving Time (DST) is widely used in Europe, North America, and in some parts of Africa, Australia and South America. It helps to make the daylight duration longer in summer by setting clock 1 hour forward in the spring (start of DST period) and by setting them 1 hour backward in autumn, when the DST period is over.
