Montana is currently in “Daylight Saving Time,” but on Sunday, November 1st, Standard Time will once again be implemented, and clocks will “fall back” one hour.
The change officially occurs at 2 a.m. on that date. For many people, the change no longer requires actually moving the dials on a clock - many electronic devices such as cell phones and some "smart devices" automatically make the change.
The NASA website explains the origin of Daylight Saving Time:
In 1966, President Lyndon Johnson signed an act into law whereby Daylight Saving Time begins on the last Sunday of April and ends on the last Sunday of October each year. However, any State can opt out of Daylight Saving Time by passing a State law. Hawaii does not observe Daylight Saving Time and neither does Arizona (although the Navajo Nation, in northeastern Arizona, does). For many years, most of Indiana did not observe Daylight Saving Time with the exception of 10 counties. Beginning in 2006, all of Indiana now observes Daylight Saving Time.
Until 2007, the return to Standard Time occurred on the last Sunday of October, but in 2005, Congress changed the date to the first Sunday of November.
The next “spring forward” will occur on Sunday, March 14, 2021.
Some people enjoy the twice-yearly ritual of tinkering with time, feeling that “springing forward” or “falling back” helps to usher in a more seasonal atmosphere. Other people, however, don’t like the idea of trying to trick our bodies and our daily routines by adjusting the clocks.
In February 2019, a Montana Senate panel killed a bill that would have asked Montana voters whether they want to end daylight-saving time in the state.
That was not the first attempt by Montana legislators to make the change. A bill was intoduced in the Legislature in 2017 to exempt Montana from the time-change; the bill died in committee.
And in the 2011 Legislature, MT State Representative Kris Hansen (R-Havre) introduced a similar proposal to take Montana off of the time-changing standard. The proposal stated: “The state of Montana rejects switching between standard time and daylight saving time and elects to remain on daylight saving time in Montana throughout the year.” The bill was tabled in committee and no further action was taken.
