If timezones go around the world each hour, how do people differentiate which one changes the date?

Question

Like I get that 12AM is a new day, but if timezones go up by one hour every zone, that means that at one point, there’d be two next to each other who are on different days, right?

We have the “International Date Line” which is roughly 180 degrees from the Prime Meridian which we base “0” off of for setting our clocks which has the time zone GMT/UTC-0
