Example 3: datetime to date javascript

var currentDate = new Date();

var date = currentDate.getDate();
var month = currentDate.getMonth(); //Be careful! January is 0 not 1
var year = currentDate.getFullYear();

var dateString = date + "-" +(month + 1) + "-" + year;

Example 4: js get day month year

const d = new Date();

d.getMonth() + 1;	// Month	[mm]	(1 - 12)
d.getDate();		// Day		[dd]	(1 - 31)
d.getFullYear();	// Year		[yyyy]

Example 5: js set datetime

//new Date(year, month, day, hours, minutes, seconds, milliseconds)
new Date(1776, 6, 4, 12, 30, 0, 0);

// Timestamp method
new Date(-6106015800000);
