Date and time types are data formats used to represent specific points in time. Common types include date, which captures just the day, month, and year; time, which records hours, minutes, and seconds; and datetime, which combines both date and time into a single value. These types are essential for organizing and manipulating temporal data in various applications. In programming and databases, date and time types help manage events, schedules, and timestamps. Different systems may use specific formats, such as ISO 8601, which standardizes how dates and times are represented. Understanding these types is crucial for accurate data handling and analysis.
