It is simply for the reason that at one given point in time, there can be a day in one country and a night in the other. The time zones help in the correct representation of the position of the sun in the sky. There are a total of 24 time zones in the world at present which are divided based on longitude line. The time happens differently in the countries divided across this imaginary line. The world is divided between the two lines of equators known as the Greenwich or the imaginary line. This map is highly recommended for everyone who wants to learn the time zones in their general learning or professional requirements. With the world time zones map you will be able to not just understand the time zones but will also be able to track them on a real-time basis. At 75 degrees east (or 75° E) longitude, the time would be 75 degrees divided by 15 degrees = 5 hours ahead of UTC, or UTC+5.īelow are all the different local times currently in use worldwide.Do you often wonder how there are different times in the world at the same particular moment and how this difference in times happens? If yes then this Printable World Time Zone Map will help you in overcoming this same dilemma of yours.At 150 degrees west (or 150° W) longitude, the time should be 150 degrees divided by 15 degrees = 10 hours behind UTC, or UTC-10.You have to divide the longitude, in degrees, by 15 to find the appropriate time zone, in hours. This is also the reference point for Coordinated Universal Time (UTC) with 1 hour per 15 degrees longitude. Defined by UTC OffsetĮvery place on Earth is measured in terms of its distance east or west of the prime meridian (0° longitude) in Greenwich, London, United Kingdom. Some geographically large (wide) countries, like India and China, use only 1 time zone, while it would have been natural to expect several, like in the US or Australia. The actual borders on a time zone map have been drawn to correspond with both internal and international borders, and rarely match up exactly with the 15-degree time zone borders. This can be seen as the white and gray stripes on our Time Zone Map and in the image above. Theoretically, each 1-hour time zone is 15 degrees wide, indicating a 1-hour difference in mean solar time. When Your Clock Doesn’t Reflect Solar Time Time Zone Borders Vary However, Arizona's local time is always UTC-7, because there's no DST in Arizona, and they remain on standard time all year. The reason it may be confusing is that California's local time during DST is UTC-7, but the standard time in California is UTC-8. For instance, during DST, it is common to say “California and Arizona are now in the same time zone.” However, the correct thing to say would be: “California and Arizona now have the same local time.” The term time zone is often confused with local time. The words “daylight” or “summer” are then usually included in the name, and the local time is usually set forward 1 hour.įor example, California uses Pacific Daylight Time (PDT) during the DST period with a UTC offset of UTC-7, but Pacific Standard Time (PST) with an offset of UTC-8 during the rest of the year. See how many time zones there currently are in the world Daylight Saving Time Zonesĭuring Daylight Saving Time (DST) the time zone name and time changes. Also, several time zones are only 30 or 45 minutes apart, increasing the number of standard time zones even further. However, the International Date Line (IDL) creates 3 more. This would bring the total number of time zones to 24. In an ideal world, each time zone would cover 15 degrees of longitude, with a time difference of one hour to adjacent time zones. Our Time Zone Map shows all current time zones. Business Date to Date (exclude holidays).
