Suppose that you've purchased a commercial sundial and you want to make it work correctly for your latitude.  Further, you don't live on your time zone meridian, but are some kilometers/miles east or west of that longitude line.  Steve Lelievre has written a web app that allows you to build a wedge to hold the sundial.  You can use the calculator to simply make a latitude wedge...

Aptly titled "Light & Time", the work is a Hublot-inspired 20-metre sundial resting in the shadows of the Matterhorn mountain." This sculptural is billed as...

The date is Sep. 22, 2022, the date of the fall equinox.  Although this is supposed to be the day of equal day and night, we know it's not exactly correct.  We measure daytime from sunrise to sunset, measured as the first and last light from the sun peaking over the horizon.  When we include sunrise and sunset plus atmospheric refration, at mid latitudes daylight wins by about 10...

What makes a sundial?  Practically anything.  Sasch Stephens discusses how he became interested in dialing.  Since then he has turned many objects into solar time devices.  It takes some creative thinking to invision how a common object can become a working sundial.  One of the most recent projects turned a 54 x 28 foot south side of a building it into a giant sundial...

Perhaps the smallest sundial goes to IBM with the printing of a sundial in a corner of a computer chip.  However it lacked a gnomon and could not really tell the time.  However, Chen Fong-shean, a Taiwanese miniature craftsman, was challenged by the French astronomical society to beat the Guiness World Record for smallest sundial held by an Italian.  The Italian dial created in...

Professor Woody Sullivan of the University of Washington in Seattle, whose long time motto has been "Seattle, sundial capital of North America", received a tribute from local television station King5 for sundials that he has designed or brought to light around Seattle. His pride and joy is his ceiling reflection dial [photo at left] As related by Joan Kinsey from King5 news, "It took Sullivan and an artist three years to chart hundreds of reflected dots across the top of Sullivan's remodeled garage..." The celestial view includes hour lines, solar declination lines of the equinox and the soltices, and a variety of transit dots that represent special dates and times to the Sullivan family.

Sullivan, a professional astronomer, has helped design a number of Seattle dials. As Joan Kinsey notes, "His first one [a declining vertical dial] went up in 1994 on the side of the astronomy building at the university ...The huge wall sundial ignited Sullivan's passion to make more and research the ones that already exist in town." Woody has created a Sundial Trail of prominent Seattle dials ranging from several vertical dials increasing the educational value at local schools to a large Shepard's dial and an occulus gnomonic dial.

Of course being Seattle, Woody scribed an appropriate sundial motto, "I thrive in the sun, Can't work in the rain. So, if I'm beclouded, please come back again. "
