Easy to use JS Date functions

The JS Date object is used to process the Date and time.
Syntax for creating a Date object:
Var myDate = new Date ()
The Date object automatically saves the current Date and time as its initial value.
The following five parameters are supported:
Copy codeThe Code is as follows:
New Date ("month dd, yyyy hh: mm: ss ");
New Date ("month dd, yyyy ");
New Date (yyyy, mth, dd, hh, mm, ss );
New Date (yyyy, mth, dd );
New Date (MS );

Note that in the last form, the parameter represents the number of milliseconds between the creation time and the GMT time on January 1, January 1, 1970. The meanings of various functions are as follows:

Month: represents the name of a month in English, from January to December.

Mth: indicates the month in an integer from 0 to 11 (January 1, January to January 1, December)

Dd: the day of a month, from 1 to 31.

Yyyy: The Year in four-digit format.

Hh: hours, from 0 (midnight) to 23)

Mm: The number of minutes, an integer from 0 to 59.

Ss: number of seconds, an integer from 0 to 59

Ms: Number of milliseconds, an integer greater than or equal to 0

For example:
Copy codeThe Code is as follows:
New Date ("January 12,2006 22:19:35 ");
New Date ("January 12,2006 ");
New Date );
New Date (2007,0, 12 );
New Date (1137075575000 );
