The time of day when the sun is at its highest point, usually around 12 o'clock in the afternoon.
We usually have lunch at noon.
The word 'noon' originates from Old English 'non', which referred to the ninth hour of the day (around 3 PM) in the Roman system of timekeeping. Over time, it shifted to denote midday, specifically the time when the sun is at its highest point in the sky.
Think of 'noon' as the time when the sun is highest in the sky, marking the middle of the day.
