Notes

Polling places in states that span multiple time zones will close either synchronously or asynchronously.

(Note ^*S) With synchronized closing, all the polls close at the same GMT/UTC time. When polls close in the advanced local time zone, they will close one hour earlier in the lagging local time zone.
(Note ^*A) With asynchronous closing, the polls close at different GMT/UTC times in different parts of the state. Media outlets might decide to declare a winner before all the polls have closed.
