The concept of date refers to a specific day in the calendar, which helps us organize and identify events. Dates are usually expressed in a format that includes the day, month, and year, such as January 1, 2023. This system allows people to communicate about past, present, and future events clearly. Time measures the progression of events and is divided into hours, minutes, and seconds. It helps us understand when things happen and is often represented on a clock or watch. Time can be categorized into different zones, such as Eastern Standard Time or Pacific Standard Time, to account for geographical differences.
