Table uses the following official abbreviations:
- EST = Eastern Standard Time (UTC-5)
- CST = Central Standard Time (UTC-6)
- MST = Mountain Standard Time (UTC-7)
- PST = Pacific Standard Time (UTC-8)
- AKST = Alaska Standard Time (UTC-9)
- HST = Hawaii-Aleutian Standard Time (UTC-10)
Time zones in the United States create a diverse picture, with each state adhering to its own unique time standard. From the Eastern Time Zone (EST) along the East Coast to the Pacific Time Zone (PST) on the West Coast, and even extending to Hawaii-Aleutian Standard Time (HST) and Alaska Standard Time (AKST), the country spans a range of six time zones. Each state’s time zone is determined by factors such as its geographical location and historical considerations. For instance, most of Florida follows EST, but parts of the panhandle observe Central Standard Time (CST). Similarly, while most of Texas operates on CST, certain western counties, like El Paso and Hudspeth, follow Mountain Standard Time (MST).
