Can't have two time zones in the US because 1 day equals 24 hours and the earth is spherical so it is 360 degrees, and 360/24=15, so there is an hour difference every 15 degrees longitude, hence the different time zones you add or subtract an hour depending on which way you are going.

The United States roughly covers 40 degrees of longitude from the west coast to the east coast so there are three time zones (2.67 actually).

I assume you are talking about the lower 48.

“The United States roughly covers 40 degrees of longitude from the west coast to the east coast so there are three time zones (2.67 actually).”

Check your globe The continental US covers around 60 degrees so there are 4 time zones- eastern, central, mountain and Pacific.

Two time zones? Some things are like they are for scientific reasons.
