25 atlas cities
This zone groups cities sharing a single civil time despite spanning a wide range of longitudes. All Korean cities listed, along with Dili and Ngerulmud, see the sun peak after clock noon, placing them west of the zone's meridian. Most Japanese cities, from Sapporo to Kyoto, peak before clock noon, sitting east of it—except Fukuoka and Hiroshima, which pattern with the Korean group instead.
