About
Ez Clock is a 21-hour, geographically local, solar-relative timekeeping system invented by Ez Aldeen Alsubainy. Sunset is 0, sunrise is 7, solar noon is 14, and the next sunset closes the cycle at 21.
The inversion
A conventional clock holds its units still and lets the sun drift. Sunset arrives at 16:40 in December and 21:00 in June, and the clock has nothing to say about it. The numbers are honest about duration and silent about the day.
Ez Clock does the opposite. It pins the sun to fixed numbers and lets the units move instead. Sunset is always 0, wherever you are and whatever the season. What changes is how long an hour lasts.
The sun does not follow the clock. The clock follows the sun.
Why twenty-one hours
Twenty-four is a historical convention, not a law of physics. It divides badly for this purpose. Twenty-one divides into three equal sevens, and the solar day has exactly three phases worth naming: sunset to sunrise, sunrise to solar noon, and solar noon back down to sunset.
Each stage holds seven Ez Hours. Each Ez Hour holds 100 Ez Minutes. Each Ez Minute holds 100 Ez Seconds. So every stage contains exactly 70,000 Ez Seconds, always, everywhere, in every season. The structure never moves.
Why the seconds change length
If a stage always holds 70,000 seconds, and stages have different physical lengths, then the seconds themselves must stretch and compress. That is not a compromise. It is the whole idea.
In London on the shortest day of the year, a night Ez Second lasts roughly 832 milliseconds and an afternoon Ez Second roughly 201. Time moves about four times faster across that winter afternoon than across the long night around it. A conventional clock hides this. Ez Clock puts it on the face.
Daylight is not an unlimited resource
An hour in December costs more than an hour in June. It takes a larger share of the daylight available to you. Everyone knows this and no clock has ever said it.
In Ez Clock, one Ez Hour is always one seventh of a solar stage. A meeting of one Ez Hour consumes the same fraction of someone's day in winter as in summer, even though the number of conventional minutes differs. Asking for someone's time becomes a request with a visible cost.
There is a related benefit. Nobody using this clock should ever look up at sunset and think the day is finished before they started. The approach of Ez 20 has been visible for hours.
Geography, not politics
Ez Clock has no time zones, no borders, and no daylight saving. A government changing its clocks does not move the sun. Two points either side of a border share almost identical Ez Time. Two cities inside one conventional zone may differ meaningfully.
Nor does it care about your elevation or what you can see. Imagine a vertical ladder a kilometre high. The person at the top sees sunset later than the person at its foot. Their Ez Time is identical, because they stand at the same point on Earth. The horizon Ez Clock uses is mathematical, not optical.
The polar problem
Beyond the Arctic and Antarctic circles there are stretches of the year with no sunrise or no sunset at all. Applied literally, the rules would produce an Ez Day lasting months, with hours measured in days. That would be astronomically faithful and completely useless.
So when your own coordinates lack a complete cycle, Ez Clock finds the nearest point on Earth that has one, by great-circle distance, and borrows its rhythm. No borders, no cities, no requirement that the point be on land. It may sit in open ocean. And it is never hidden: the clock tells you it has done this, where the reference is, and how far away.
How a website can follow the sun
A sundial needs no clock. It has the actual sun, casting an actual shadow, and it works knowing nothing about hours.
A browser has no view of the sky. It cannot measure the sun, so it reconstructs it. Reconstruction needs one input: which moment of Earth's rotation and orbit to reconstruct. Latitude and longitude say where on the sphere you stand. They cannot say how far the sphere has turned.
So this site takes the device's instant, converts it immediately to a Julian day, which is a raw astronomical count, and from there everything is orbital mechanics: declination, hour angle, altitude, and the horizon crossings that define your anchors. No time zone is ever read. No UTC offset is applied. No daylight saving is honoured. Nothing from the conventional clock is displayed. The instant is the input an ephemeris needs, nothing more.
A physical Ez Clock with a real gnomon and a light sensor would need none of this. That device is worth building. It cannot be a web page.
Privacy
There is no backend. No server sees your coordinates, because no server is involved in the calculation. Everything runs in your browser. Once the page has loaded once, it works offline permanently, which suits a clock that answers to the sun rather than to a network.
Status
The conceptual architecture is settled at version 1.2.1. What remains is engineering: the precision of the solar model, the design of a physical movement, a standard format for written Ez timestamps, and the behaviour of stages close to the polar boundary.
