A Journey Along the Meridian
longitude.day
00° 00′ 00″
A celestial thread connecting all places at once.

Reykjavík
64° 08′ N · 21° 56′ W
Where the meridian threads through volcanic glass and arctic light. The sun lingers, then disappears for months at a time -- a place where longitude bends to the seasons.

London
51° 30′ N · 00° 00′ W
The reference. The Royal Observatory at Greenwich gave the world a shared zero -- a thin brass line in the courtyard from which every other longitude is measured. Here, all clocks once began.

Madrid
40° 25′ N · 03° 42′ W
A city that refused its longitude -- aligned by clock to Berlin, by sky to Lisbon. The dusk arrives an hour late, and dinner waits for the violet to settle over the plazas.

Algiers
36° 45′ N · 03° 03′ E
The meridian crosses the sea, and on the far side the air tastes of salt and citrus. Whitewashed terraces step down to a coast where Europe and Africa share a single line of sight.

Accra
05° 33′ N · 00° 12′ W
Where the prime meridian meets the equator -- the conceptual origin of the world's grid. The point itself lies offshore in the Atlantic, an empty patch of sea named Null Island, marked only on charts.

Libreville
00° 23′ N · 09° 27′ E
Just north of zero. The forest exhales humidity at the same hour, every day, every season. Here longitude becomes irrelevant -- the sun's geometry is almost vertical, the days almost identical.

90° 00′ S · All longitudes
The journey ends where every longitude converges. At the geographic south pole, a single step in any direction leads north. The meridian dissolves into a point, and the grid collapses into one.
—
A meridian is a thread of simultaneity.
Every point on this line shares the same noon, the same sunrise, the same shadow at the same instant. longitude.day is a small celebration of that quiet coordination -- the way a single imagined line, drawn pole to pole, stitches the world into one moving day.
