A time zone is a region that observes the same standard time. The Earth is divided into 24 time zones, each differing by one hour. The International Date Line is located in the middle of the Pacific Ocean and marks the boundary between one day and the next.
Coordinated Universal Time (UTC) is the world standard time, unaffected by daylight saving time. Time zones around the world are based on UTC, such as UTC+8 which is 8 hours ahead of UTC.
Daylight Saving Time is a practice of advancing clocks during summer months to save energy. About 70 countries worldwide implement daylight saving time, but the dates and times of implementation vary.
Because the Earth is round, when it is daytime in one place, it is nighttime on the opposite side. This is why when you are working in Asia, people in the Americas might be sleeping. The maximum time difference can be up to 24 hours.
