The sun dial was used for telling time. The sundial would cast a shadow so people know what time of day it was by where the shadow fell.
sundial could be in a shadow and give no clues
you never ever need a battery
You cannot accurately tell time on a sundial when it is rainy because the sun's rays are blocked by the clouds or rain. The shadow that the sundial casts is crucial for telling time, so without the sun, it's not possible to do so.
A sundial relies on the position of the sun to cast a shadow, meaning it only works during daylight hours. It is also affected by factors such as the season, latitude, and obstacles blocking sunlight, making it less accurate than a clock.
reading the stars or the clock i would check somewhere else though to make sure
The Romans told time by three methods. The first was the sundial. The second was the water clock. The third was simply by looking at where the sun was in the sky.
He used a portable sundial.
The raised arm of a sundial that indicates the time of day by its shadow is the gnomon (NO-mon). A sundial has but one arm, what do you mean by secondary arm?
The sundial was used in the old days to tell the time of day. The sun's movement across the daytime sky would project a shadow onto the surface, (ground), below the stake, (which was stuck in the ground on the earliest versions). The sundial only worked in the daylight hours, (obviously), and I've never heard of a "Moondial" or anything of that nature so I guess they had no means of telling time at night.
