Bonus Question: Why?
If sunset in Boise, Idaho is 9:30 p.m. on June 21, and 9:03 p.m in Minneapolis the same day, that must mean Boise is further north, right?
Unh-unh.
Minneapolis is (further north), by about 100 miles.
Instead, the sunset difference is due entirely to each city’s relative location within its time zone.
A Matter of Latitude Longitude
So, Boise (latitude 43º) sits at the very western end of Mountain time; just 50 miles away in eastern Oregon, it’s Pacific Standard Time.
By contrast, Minneapolis (latitude 45º) is located roughly in the middle of Central Standard Time.
P.S.: Wanna guess where I visited recently? 🙂
