What happens at this instant

The Sun’s apparent longitude crosses 0° and it stands directly over the equator, moving north. Day and night are nearly— not exactly — equal everywhere: refraction and the Sun’s own width mean the true equal-day date (the “equilux”) falls a few days to one side of the equinox — which side depends on your hemisphere. It is a single worldwide moment: the same instant, whatever your clock says locally — which is what the city table below converts.

City links open that city’s live sunrise/sunset page. Day lengths are computed by LEV’s own solar geometry (the engine behind those pages) for the event’s local calendar day.

Where this time comes from

The instant and the year table are the published minutes of the USNO, Astronomical Applications Department (UT), frozen 2026-07-17. LEV computes each instant independently as a cross-check (Meeus’s standard algorithm): across all 104 published events the two agree within ±91 seconds, and the four 2026 instants were further verified against JPL Horizons (DE441)to ~31 s. The countdown ticks on the computed instant’s seconds. Beyond the early 2030s every published minute — anyone’s — inherits the uncertainty of Earth-rotation (ΔT) predictions and can shift by up to about a minute as the years arrive.
