A previous experiment with permanent Daylight savings time.

During the energy crisis of the 1970's, the U.S. congress passed a law which would keep daylight savings time uninterrupted for two years.

In December 1973, public support for the measure was at 79%.

On January 6, 1974, the law went into effect.

In February 1974, public support dropped to 42%.

By October 1974, congress had received enough complaints from constituents that they repealed the bill.

In some parts of the country, sunrise was as late as 9:30.

In 2011, Russia tried this, but they gave up in 2014.

This has always been true. In college, kids from Anchorage said that they did not see the Sun in Winter, with it rising ~10 AM & setting ~2 PM.

It depends upon what latitude you are.

Check out the "length of day" graphic at

If you are over 50° N, this can happen, and--besides the hour of DST--one's position within the timezone (longitudinal difference from the meridian used to define the timezone) also affects when the events of local sunrise, solar noon, and sunset occur, with respect to the official zone time.

@SomeMichGuy Of course it is true in Alaska even without time changes, but the law in 1974 exacerbated the problem in parts of the lower 48. At any rate, despite what you or I may feel about what people OUGHT to think, what DID happen was that many people who favored permanent DST back in 1974 abruptly changed their minds when reality forced them to see that they had not thought it through.

I suspect the same thing would happen again.

And as someone who lives north of the 45th parallel, I do want us to adjust the time twice a year.
