PRIME MERIDIAN

LONGITUDE
.DAY

The Prime Meridian. An arbitrary line drawn through Greenwich in 1884. The world agreed to start counting here — a political fiction disguised as geographic fact.

51.4772° N, 0.0000°
UTC+0 --:--:--

015°

Central European Time. The line passes through empty Saharan sand, the Adriatic coast, the industrial heartland of Scandinavia. One hour east of zero.

UTC+1 --:--:--

030°

Eastern European Time. Cairo, Johannesburg, Helsinki. Where Africa bisects and the Nile traces its long meridian shadow northward.

UTC+2 --:--:--

045°

Moscow Time. The Caucasus, Baghdad, the Persian Gulf. Oil and empire measured in degrees from Greenwich.

UTC+3 --:--:--

060°

The Urals give way to the Central Asian steppe. Afghanistan, Pakistan. Four hours ahead — or behind, depending on your meridian of origin.

UTC+4 --:--:--

075°

India Standard Time territory. The subcontinent chose a single half-hour offset — UTC+5:30 — refusing to align with the 15-degree grid. A quiet rebellion against the meridian system.

UTC+5 --:--:--

090°

Quarter-turn of the Earth. Bangladesh, western China, the Bay of Bengal. Exactly perpendicular to Greenwich — the planet's right angle.

EARTH CIRCUMFERENCE AT EQUATOR 40,075 KM
UTC+6 --:--:--

105°

Southeast Asia. Vietnam, Thailand, western Indonesia. The line cuts through monsoon forests and the Mekong Delta. Seven hours from zero.

UTC+7 --:--:--

120°

China Standard Time. Beijing, Shanghai, Perth. China forces a single timezone across 60 degrees of longitude — the largest temporal distortion on Earth.

UTC+8 --:--:--

135°

Japan Standard Time. Tokyo, Seoul, Yakutsk. Nine hours ahead. The line grazes the Australian outback — red dust at 135 degrees.

UTC+9 --:--:--

150°

Australian Eastern Standard Time. Sydney, Papua New Guinea. The Pacific begins to dominate — more water than land from here to the date line.

UTC+10 --:--:--

165°

Solomon Islands, New Caledonia. The scattered archipelagos of Melanesia. Eleven hours from Greenwich — almost tomorrow.

UTC+11 --:--:--

180°

The International Date Line. Where today becomes tomorrow, or yesterday — depending on which direction you crossed. The meridian system's most violent fiction: a line where time itself fractures.

ANTIPODE OF GREENWICH 180.0000°
UTC+12 --:--:--

You have traversed half the Earth. The other half is a mirror. Every degree east is a degree west from the other side. The grid is a loop. The day is a circle. longitude.day
