At what time of the day is your shadow lazy?

Answer. Sunrise and sunset will produce the longest shadows of the day, because that’s the most extreme angle possible before the horizon blocks the sun.

Why our shadows are longer in the evening and morning?

Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. … As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!
