I'm sure you can find one at your local dollar store. :)
My father had a luminous watch, so in the middle of the night he could tell what time it was.
A sundial is not accurate when it is cloudy, rainy, or at night when there is no direct sunlight to cast a shadow. Additionally, if the sundial is not properly calibrated for its location or if it is moved, it may not accurately tell time.
Airhead bungle bought the floodlight for his sundial because he mistakenly thought it would help him read the time at night. However, the floodlight would actually obscure the sundial's functionality by casting shadows and disrupting the natural sunlight needed to tell time accurately.
so he could tell time at night
Unfortunately, a sundial relies on the position of the sun's shadow to tell time, so it isn't possible to accurately tell time using a sundial on a cloudy day when the sun is obscured.
He used a portable sundial.
Yes, sundials can tell time. That is what they are designed to do.
You can use a sundial, which is a device that uses the position of the sun's shadow to tell time. By placing a stick or pointer on the sundial, the shadow it casts can indicate the time based on markings on the sundial's face.
Some disadvantages of using a sundial to tell time include its dependence on sunlight, making it ineffective during cloudy or rainy days and at night. Additionally, the accuracy of a sundial can be affected by its geographic location and the time of year, as the position of the sun changes. Sundials also require adjustment for daylight saving time and do not account for time zones, leading to potential discrepancies in timekeeping.
to tell the time years ago.....
