No, sundials do not work at night because they rely on sunlight to cast a shadow from a gnomon (the part that sticks up). Without sunlight, there is no shadow to indicate the time. At night, other methods, such as clocks or moon phases, are used to tell time.
Sundials require sunlight.
Some of the problems with using sundials include their reliance on sunlight, which makes them ineffective at night or on overcast days. They also require regular adjustment due to changes in the position of the sun throughout the year. Additionally, their precision can be affected by factors such as location, terrain, and the accuracy of the sundial's design.
People stopped using sundials primarily due to the advent of more accurate and reliable timekeeping devices, such as mechanical clocks and later, digital watches. Sundials are dependent on sunlight and can only provide approximate time, making them impractical for precise scheduling, especially in cloudy weather or at night. The rise of industrialization and the need for synchronized time across various sectors further diminished the use of sundials. Additionally, the convenience of modern timekeeping technology has made traditional methods obsolete.
Yes, sundials can tell time. That is what they are designed to do.
Good points: Sundials are environmentally friendly, do not require any power source, and can be an aesthetically pleasing addition to a garden or outdoor space. Bad points: Sundials are not accurate during overcast or cloudy weather, do not work at night, and can be affected by changes in latitude and daylight savings time.
They don't work on cloudy days or at night
Sundials require sunlight.
Because there is no sun at night. So you can't use a SUNdial at night. Also, sundials have to be outside. Clocks work at night and don't have to be outside.

we have to adjust sundials to see the shadow and time
Sundials were used to tell time, back without watches.
maybe because they wanted to tell the time.
They couldn't tell the time from sundials because there was no sun.
Sundials work with a ratio by calculating the amount of shadow cast on the ground in relation to the sun's position. These were largely used prior to the advent of the clock.
