To make it easy to handle date and time, JavaScript has a built in Date object. A Date variable has to be created explicitly before we can use it. this can be done using the following JavaScript statement.
dateVar = new Date();
this creates a variable called dateVar and initializes it to contain the curent date and time. if you want to initialize it with some other date and time, you can use any of the following alternate syntaxes.
dateVar = new Date("month day, year hours:minutes:seconds")
dateVar = new Date(year, month, day)
dateVar = new Date(year, month, day, hours, minutes, seconds)
