Arizona, the lone mainland state to not observe daylight saving time, will have to conform with the rest of the continental United States if a new bill is passed.

Three state Republican lawmakers introduced a bill Tuesday which would mandate Arizona adopt the practice. Daylight savings time went into effect nationwide in 1918, but Arizona opted out in 1968. Hawaii also does not observe daylight saving time.

A November Rasmussen poll found 43 percent of Americans say there’s no need for daylight saving time. In Utah, lawmakers said they will propose a bill this year to no longer observe it following a study that suggested support in the state for the move. Colorado, Idaho, Montana and Wyoming are also considering the possibility.

A 2009 study published in the Journal of Applied Psychology found indirect evidence that daylight saving time leads to an increase in workplace injuries and a loss of 40 minutes of sleep the Monday after switching to standard time.
