Central Standard Time (CST) and Central Daylight Time (CDT) are two of the most commonly used time zones in the United States. When planning a call between Indianapolis, Indiana and CST, it is important to remember that the geographical area is two hours ahead of CST. In the late 1940s, the use of daylight saving time, also known as fast time, became popular in cities across the country. This means that some communities in Indiana choose to follow fast time throughout the year, essentially aligning with the Eastern time zone.
However, Indiana is officially in the Central time zone. This means that most of the state follows CST and CDT throughout the year. The exceptions are those communities that choose to follow fast time instead. It is important to remember that when planning a call between Indianapolis and CST, you should keep in mind that geographical areas are in different time zones.
