Date constructor:new Date()
new Date("month day, year hours:minutes:seconds")
new Date(yr_num, mo_num, day_num)
new Date(yr_num, mo_num, day_num, hr_num, min_num, sec_num)
Date object for today's date and time. If you supply some arguments, but not others, the missing arguments are set to 0. If you supply any arguments, you must supply at least the year, month, and day. You can omit the hours, minutes, and seconds.The way JavaScript handles dates is very similar to the way Java handles dates: both languages have many of the same date methods, and both store dates internally as the number of milliseconds since January 1, 1970 00:00:00. Dates prior to 1970 are not allowed.

getYear method returns either a 2-digit or 4-digit year:getYear is the year minus 1900. For example, if the year is 1976, the value returned is 76.getYear is the four-digit year. For example, if the year is 1856, the value returned is 1856. If the year is 2026, the value returned is 2026.year.Xmas = new Date("December 25, 1995 23:15:00")
year = Xmas.getYear()
Example 2. The second statement assigns the value 2000 to the variable year.Xmas = new Date("December 25, 2000 23:15:00")
year = Xmas.getYear()
Example 3. The second statement assigns the value 95 to the variable year, representing the year 1995.Xmas.setYear(95)
year = Xmas.getYear()

dateString | A string representing a date. |
parse method takes a date string (such as "Dec 25, 1995") and returns the number of milliseconds since January 1, 1970, 00:00:00 (local time). This function is useful for setting date values based on string values, for example in conjunction with the setTime method and the Date object.IPOdate is an existing Date object, then you can set it to August 9, 1995 as follows:IPOdate.setTime(Date.parse("Aug 9, 1995"))

toLocaleString()
toLocaleString, be aware that different platforms assemble the string in different ways. Using methods such as getHours, getMinutes, and getSeconds gives more portable results.today is a Date object:today = new Date(95,11,18,17,28,35) //months are represented by 0 to 11In this example,
today.toLocaleString()
toLocaleString returns a string value that is similar to the following form. The exact format depends on the platform. 12/18/95 17:28:35

Date.UTC(year, month, day, hrs, min, sec)
UTC takes comma-delimited date parameters and returns the number of milliseconds since January 1, 1970, 00:00:00, Universal Coordinated Time (GMT).
Because UTC is a static method of Date, you always use it as Date.UTC(), rather than as a method of a Date object you created.
Date object using GMT instead of local time:gmtDate = new Date(Date.UTC(96, 11, 1, 0, 0, 0))
