So why are there two parts to the Mountain Time zone ?!?!
Hey I'm a Brit I don't know !!

"cause the other mountain time zone does not recognize the time change in the spring and fall.

Curlyben

That makes a twisted sort of sense I suppose.
Ta much

Makes no sense when you travel there. lol. But - to each their own and I guess each state has the right to do that. Daylight Savings Time does not make much sense anyways. Why cut off one end of the blanket just to sew it onto the other end?

History of Daylight Time in the U.S.

Although standard time in time zones was instituted in the U.S. and Canada by the railroads in 1883, it was not established in U.S. law until the Act of March 19, 1918, sometimes called the Standard Time Act.

This is article is too funny:

Capt...your resources are unlimited, that was funny.

Some of the myths I have heard are;

1. Has something to do with more daylight for the farmers (but now they have tractor cabs with lights, heaters, air conditioning, music, t.v., wet bar,......), I don't think that is valid anymore even if it was at some time.

2. I've heard the excuse that it allows more daylight for children when they are coming home from school. But in the dead of winter it's dark by 4-4:30 pm?

I don't understand why they just down discontinue it.

I did enjoy the map...thanks, Stringer
