What time zone is Louisiana?

Louisiana falls within the Central Time Zone (CT) in the United States. The Central Time Zone is typically UTC-6 during Standard Time (Central Standard Time or CST) and UTC-5 during Daylight Saving Time (Central Daylight Time or CDT), which is observed from the second Sunday in March to the first Sunday in November. Louisiana, along with many other states in the central United States, follows this time zone.

Note that the start and end dates of daylight saving time can change


Maine's area code history has been relatively simple and consistent. Since the establishment of the North American Numbering Plan (NANP) in 1947, the state has been served by a single area code, **Area Code 207**, which has covered the entirety of Maine. Unlike other regions that underwent area code splits or overlays due to population growth and increased telecommunications demand, Maine has maintained its original area code, making it a unique case of long-standing continuity in the world of telecommunications within the state.
