Daylight is natural light that occurs during the day. It's what makes the world look bright and colorful.
When we talk about daylight, we often think of it as a time when people are awake and active. We use daylight to plan our schedules, whether it's going to work or school, exercising outside, or just spending time with family and friends. People might say things like "I have a meeting during the daytime" or "Let's go for a walk in the morning so we can enjoy some daylight." Daylight is also often used as an opposite word to nighttime, which means it's the time of day when stars come out.
