Here’s the whole worlds times zones
The earth has been divided into twenty-four time zones of one hour each. Each zone thus covers 15° of longitude.
Why these have so many zones?
Why So Many Times On Earth?
Why So Many Times Zone In the world?
The reason behind this is the longitude and time.
The best means of measuring time is by the movement of the moon, the planet the earth, or the sun regularly rises and sets every day.
When the Prime Meridian of Greenwich has the sun at the highest point in the sky, all the places along this meridian will have mid-day or noon.
As the earth rotates from west to east, and those to the west will be behind it.
It can be calculated by this way
The earth rotates 360° in about 24 hours, which means 15° an hour or 1° in four minutes. Thus, when it is noon at Greenwich, the time at 15° east of Greenwich will be 15 × 4 = 60 minutes, i.e., 1 hour ahead of Greenwich time, but at 15° west of Greenwich, the time will be behind Greenwich time by an hour
These all are match
The local time at the longitude, which generally passes through the middle of the country is deemed to be the standard time in that country.
today we discuss about which countries have highest time zones with the name of country and serial number .
