JavaScript Date
The JavaScript Date object serves as a fundamental component for managing date and time values within applications. It encapsulates a moment in time, allowing developers to perform various operations such as date arithmetic, formatting, and manipulation.
The time value represented by a Date object is measured in milliseconds since the Unix Epoch, which is defined as January 1, 1970, at 00:00:00 UTC (Coordinated Universal Time). This epoch serves as a reference point for calculating time intervals and representing dates across different time zones.
Creating a Date object involves invoking the new Date() constructor, which initializes the object with the current date and time based on the system’s local time zone. Additionally, the Date constructor supports various parameter options to specify a specific date and time, including year, month, day, hour, minute, second, and milliseconds.
