What Are the Timezones in United States
The United States spans multiple timezones, which are divided into four main categories: Eastern, Central, Mountain, and Pacific. These timezones help establish a standardized system for setting local time across the country. Understanding these timezones is crucial for activities such as travel, business coordination, and communication. In this article, we will explore each of these timezones in detail and answer some frequently asked questions related to them.
Eastern Timezone (ET)
The Eastern Timezone is the standard time used in the eastern part of the United States, including cities such as New York, Washington D.C., and Miami. It is five hours behind Coordinated Universal Time (UTC-5) during standard time, and four hours behind (UTC-4) during daylight saving time.
Central Timezone (CT)
The Central Timezone is observed in the central part of the United States, including states like Texas, Illinois, and Louisiana. It is six hours behind Coordinated Universal Time (UTC-6) during standard time, and five hours behind (UTC-5) during daylight saving time.
Mountain Timezone (MT)
The Mountain Timezone is used in the mountainous regions of the United States, including states such as Colorado, Arizona, and Utah. It is seven hours behind Coordinated Universal Time (UTC-7) during standard time, and six hours behind (UTC-6) during daylight saving time.
Pacific Timezone (PT)
The Pacific Timezone is followed in the western part of the United States, including cities such as Los Angeles, San Francisco, and Seattle. It is eight hours behind Coordinated Universal Time (UTC-8) during standard time, and seven hours behind (UTC-7) during daylight saving time.
Daylight Saving Time
Daylight Saving Time (DST) is observed in most states within the United States. It begins on the second Sunday of March when clocks are set forward by one hour, and ends on the first Sunday of November when clocks are set back by one hour. This adjustment is made to make better use of daylight during the longer summer days.
