As the Sun moves across the sky (actually, it's the Earth turning), the shadows cast by objects move in the opposite direction. A sundial has a piece called a gnomen, and its shadow moves across marked sections for the hours. Because sundials were invented in the Northern Hemisphere, where the Sun appears in the southern part of the sky most of the year, the shadow moves "clockwise."

Why are sundials inaccurate for measuring time?

The position of the shadow at a given time of day will vary slightly with the seasons. For example, if at 2:00 p.m. on 31 August the shadow is exactly on the 2, at 2:00 p.m. on 31 October it will be off a little. Of course for a sundial to be mostly correct most of the time, it has to be positioned according to where it is in the world. And of course, it will never take into account the fact that (in some countries) we switch to Daylight Saving Time part of the year. Here's an improved answer: Sundials are inaccurate for 3 reasons : 1) There's obviously the difficulty of getting an exact reading for "minutes" using are relatively crude device like a sundial. 2) Sundials measure "apparent solar time". Clocks use "mean solar time". "apparent solar time" varies a bit during the year because of the Earth's orbit and axial tilt. "Mean solar time" averages out these differences to give us a day of exactly 24 hours. So, a correction needs to be applied to get from the time the sundial shows to the time on a clock. 3) The other correction that's needed is for your longitude within your particular time zone. (Also "Daylight Saving" has to be allowed for, of course.) This adjustment is not really because the sundial is inaccurate, but it is needed to get to the standardised time shown by a clock.

How can you set your watch to local time using a sundial?

To set your watch to local time using a sundial, first ensure the sundial is positioned correctly, with its gnomon (the vertical piece) pointing toward true north. Observe the shadow cast by the gnomon on the hour markings of the sundial, which indicate the time based on the position of the sun. Adjust your watch according to the reading on the sundial, accounting for any differences due to your watch’s time zone or daylight saving time if applicable. This method relies on clear sunlight and accurate positioning for best results.

A watch and a sundial. Both are used to tell time, but a watch has many moving parts such as gears and hands, while a sundial relies solely on the sun's position to cast a shadow and indicate the time.


Why does a gnomon on a sundial have to be 45 degrees?

It doesn't. The gnomon is supposed to match the latitude of the location where the sundial is placed. If the latitude is 30 degrees and the gnomon is 45 the entire sundial will have to be tilted to keep correct time. Another way to describe this is to say that the gnomon should be parallel to the Earth's axis.
