Mississippi does observe daylight saving time; it is not one of the states that have opted out of it. The only two states in the U.S. that do not observe daylight saving time are Arizona and Hawaii.
The simple reason why Arizona does not observe daylight saving time is due to its desert climate. Adding an extra hour of daylight in the evening would lead to increased energy consumption because people would run air conditioning longer during the hot summer evenings. Hawaii does not observe it because its geographic location near the equator means there is minimal variation in daylight hours throughout the year, so shifting the clock is unnecessary. Mississippi follows the Central Time Zone and participates in daylight saving time like most states.
Thus, Mississippi is not an exception to daylight saving time observance; the two states that notably do not do DST are Arizona and Hawaii for the reasons explained above.
