Queensland, New South Wales (except Broken Hill), Victoria, Tasmania, Australian Capital Territoryīrisbane, Sydney, Melbourne, Hobart, Canberra Australian Western Standard Time (AWST)ĪEST is equal to Coordinated Universal Time plus 10 hours (UTC +10).ĪCST is equal to Coordinated Universal Time plus 9.5 hours (UTC +9.5).ĪWST is equal to Coordinated Universal Time plus 8 hours (UTC +8).Australian Central Standard Time (ACST).Australian Eastern Standard Time (AEST).With a land mass close to 7.7 million square kilometres, Australia is the world’s sixth largest country and is divided into three separate time zones. 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.Back to main page AUSTRALIA Time Zones Australia map World Time Zones and Australia map.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. 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. 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 total number of standard time zones even further. However, the International Date Line (IDL) creates 3 more. If each time zone were 1 hour apart, there would be 24 in the world. Our Time Zone Map shows all current time zones. Business Date to Date (exclude holidays).
