Time in Rhode Island, as in all US states, is regulated by the United States Department of Transportation. Rhode Island is in the Eastern Time Zone (ET) and observes daylight saving time (DST). Independent of daylight saving time, solar noon in Rhode Island on the March equinox is about 11:53, which is earlier than most areas of the United States. The state is small enough that geographical location only results in a difference of a few minutes. Like the other five New England states, which also use the Eastern Time Zone, sunset in the winter in Rhode Island can occur as early as 4:30 p.m. Most of the New England states have considered using the Atlantic Time Zone without daylight saving to mitigate this. While Rhode Island considered such a bill in 2016, it would only take effect if Massachusetts did the same.
