What is the legal definition of sunrise?
Quick Answer: The legal definition of sunrise is the moment when the upper edge of the sun’s disk appears above the horizon in the morning. This time marks the official start of daylight for legal and civil purposes.
Sunrise is used in various laws and regulations to define when certain activities can begin or end. It’s not just when the sun’s center crosses the horizon but specifically when the sun’s top edge is visible.
This exact moment depends on your location and date, as the sun’s position changes throughout the year. Legal definitions rely on this standard to keep timing consistent and clear.
