That depends where you are on the planet. Your shadow would be longest if you were standing on a rotational pole at the time of equinox. At this point your shadow would be infinity long as it would be "projected" into space.
However as a rule of thumb one's shadow is longest when the sun is rising or setting but high enough to cast your shadow.
the longest shadow you see in the day is 3\early in the morning and near the sunset...
Just after sunrise, or just before sunset.
when its its sunrise and evening.
Morning
Summer would probably have the the shortest shadow because the sun is right over us and winter would have the longest because the sun isn't right over us. The length of the shadow really doesn't depend on the seasons. It is really about where the sun is in the sky. But in order for there to be an actual shadow, the sun must be visible. So in summer you would find the most shadows but not the longest. You can get a long shadow in any season as long as the sun shines.
The sun casts the longest shadows immediately after sunrise and immediately before sunset.
At dawn and dusk.
it would be long cause the Sun is getting lower and would heat your feet and feet is the beginning of your body and would make a long shadow. sometimes longer than you!
at noon the shadow is point sized {smaller} and in morning and evening the shadow is the longest.
they are strong characters in the game but silver and shadow are the same strength so one time shadow will win and another silver would win BTW shadow dies :(
A shadow is longest in the early morning or late afternoon when the angle of the sun is low in the sky. This occurs during sunrise and sunset when the sun is closest to the horizon, causing objects to cast longer shadows.
That would be Impa.
