New Year's midnight is not one instant worldwide — it is a real 26-hour wave. A region at UTC offset O reaches local midnight when UTC clock time equals M(O) = 24 − O hours (measured from Dec 31 00:00 UTC). Kiritimati (UTC+14) is first at M=10h; Baker Island (UTC−12) is last at M=36h — a genuine 26-hour span driven entirely by the real range of civil UTC offsets, from +14 down to −12.
34 real named regions are placed at their true latitude/longitude and include genuine non-integer offsets (Chatham Islands UTC+12:45, Nepal UTC+5:45, India UTC+5:30, Afghanistan UTC+4:30, Iran UTC+3:30, Newfoundland UTC−3:30, Marquesas UTC−9:30). Each flips from waiting to celebrating the instant the simulated UTC clock reaches its own M(O) — the highlighted band and the moving meridian line are both driven by this same offset arithmetic, not by sun position (that is a different, separate simulator).
- Sweep speed — simulated UTC hours advanced per real second.
- Jump to region — selects any of the 34 regions and shows its exact countdown or elapsed celebration time.
- All / Celebrating / Waiting — filters which region markers are shown.
- Click a marker on the globe — selects that region directly.
Offsets use each region's standard December civil UTC offset (DST-adjusted where it applies on Dec 31, e.g. Sydney/Adelaide) and are idealized to clean 15°-wide longitude bands for the band shading, the same convention used by the separate day/night terminator globe elsewhere on this site.
