Sunclock is a facsimile of the natural clock. Check in with it periodically, just as you would with a standard timepiece, and I've been told that you may find yourself reinterpreting how you inhabit your day.

A lone hand sweeps around the dial once per rotation of the earth (sometimes known as 24 hours). During daylight the hand crosses a bright arc tracing the period of the sun’s passage across the sky, and during the night it passes through a dark void.

This clock bears no numbers and no divisions of time but the one used by man since the dawn of the perception of time, the one used by most every every organism on our planet: a single photoperiod as determined by the continual rotation of the earth in its revolution around the sun.

When I work in my gardens, I often look to the sky to determine if it’s a good time to water, if I should be cleaning up, if the waxwings will soon return to the persimmon tree. Indeed, we have always guided our behaviors by the position of the sun in the sky. And in so doing, we connect ourselves to the cosmic cycle of heating and cooling, sleeping and waking, imbibing and exhaling.

Like the sky, sunclock tells you where the sun is in relation to your horizon. Unlike the sky, you can carry the sunclock around in your pocket and bring it indoors. You can even see exactly how far the sun has passed around the other side of the earth, when out the window all is darkness.

So, as an experiment, I ask you to go outside, look at the sky, and try re-orienting yourself to the sunclock.

See what happens, and please let me know your impressions:


I owe much gratitude to my friend chmod000, whose brilliant Diurnal Time clock ( offers a different take on living by the sun.
