What time is it in Australia at 3pm in China (how to calculate the time difference?)

Keywords: 3pm in China, what time is it in Australia, how to calculate the time difference

Globally , due to different time zones in different regions, people often encounter the problem of jet lag when communicating or traveling across countries. Time difference refers to the time difference between different regions. Due to the rotation of the earth and the different longitudes of different regions, the time in different regions is different. As two countries located in different hemispheres, China and Australia have relatively large time differences. So, what time is 3pm in China in Australia? This article will answer this question in detail and introduce how to calculate the time difference.

1. What time is 3pm in China in Australia?

The time difference between China and Australia is mainly caused by the different longitudes of the two countries. China is located between 73° and 135° east longitude, while Australia is located between 113° and 153° east longitude. According to the principle of the earth's rotation, every 15° of east longitude is equivalent to a time difference of 1 hour.

The main time zone in China is the East Eighth District, which is Beijing time (GMT+8), while Australia has more time zones, mainly Including Australian Eastern Standard Time (AEST, GMT+10) and Australian Central Standard Time (ACST, GMT+9:30), etc. Taking Australian Eastern Standard Time as an example, it is 2 hours different from Beijing time.

So, when it is 3pm in China, it is 5pm in Australia Eastern Standard Time.

2. How to calculate the time difference between China and Australia?

To calculate the time difference between China and Australia, you first need to determine the longitude of the two locations and know their respective time zones. Then, based on the longitude difference and time zone difference, the specific time difference is calculated.

The following is an example of calculating the time difference between China and Australia Eastern Standard Time:

1. Determine the longitude of two locations: China’s longitude ranges from 73° to 135°, The longitude range in eastern Australia is 113° to 153°.

2. Calculate the longitude difference: the easternmost longitude of China is 135°, and the westernmost longitude of eastern Australia is 153°. The longitude difference between the two is 18°.

3. Calculate the time difference: According to the principle of the earth's rotation, every 15° of longitude is equivalent to a time difference of 1 hour. The longitude difference between China and eastern Australia is 18°, so the time difference is 18°/15° = 1.2 hours, or 1 hour and 12 minutes.

4. Adjust according to the time zone difference: China is the East 8th District, and eastern Australia is GMT+10, a difference of 2 hours.

To sum up, the time difference between China and Australia Eastern Standard Time is 1 hour and 12 minutes plus 2 hours, which is 3 hours and 12 minutes.

3. Summary

China is Australia at 3pm5pm EST. To calculate the time difference between China and Australia, you need to determine the longitude difference between the two locations and take into account the difference in their respective time zones. According to the time difference equivalent to 1 hour for every 15° of longitude, combined with the time zone difference, the specific time difference can be calculated.

When communicating or traveling across countries, it is very important to understand the time difference. Arrange your time reasonably to avoid misunderstandings or inconveniences caused by time differences. At the same time, mastering the calculation method of time difference can better communicate and coordinate with people far away.

I hope this article can help everyone better understand what time it is in Australia at 3pm in China, and master the method of calculating the time difference. I wish you all success in your cross-border exchanges and make reasonable arrangements for your time!
