In 2017, a Massachusetts commission considering changing the Bay State’s time zone recommended keeping Daylight Saving Time year-round, but only if a majority of Northeast states also wanted to.

The Florida Legislature voted overwhelmingly last year to keep Daylight Saving Time year-round, and the bill was signed by Gov. Rick Scott.

Californians voted in November in favor of permanent Daylight Saving Time, a measure called Proposition 7. But to take effect, the California legislature and U.S. Congress would have to approve it.
