Noon is the time of day when the sun reaches its highest point in the sky. This typically occurs around 12:00 PM, depending on the location and time of year. At noon, shadows are at their shortest, and daylight is usually at its brightest. In many cultures, noon is often associated with lunchtime, as people take breaks from work or school to eat. The concept of noon is also important in various timekeeping systems, such as the 24-hour clock, where it is represented as 12:00.
