date functions javascript code example
Example 1: javascript get time
// these are the most useful ones IMO
var time = new Date();
time.getDate(); // returns value 1-31 for day of the month
time.getDay(); //returns value 0-6 for day of the week
time.getFullYear(); //returns a 4 digit value for the current year
time.getHours(); //returns value 0-23 for the current hour
time.getMinutes(); //returns value 0-59 for the current minute of the hour
time.getSeconds(); //returns value 0-59 for current second of the minute
time.getMilliseconds(); //returns value 0-999 for current ms of the second
time.getTime(); //returns date as ms since Jan 1, 1970
time.toDateString(); //returns a string (e.g. "Fri May 9 2020")
time.toLocaleString(); //returns date and time (e.g. "9/12/2015, 6:08:25 PM")
time.toLocaleTimeString(); //returns time (e.g. "6:08:25 PM")
time.toLocaleDateString(); //returns date (e.g. "9/12/2015")

d.getMonth(); //Get the month as a number (0-11)
d.getDate(); //Get the day as a number (1-31)
d.getHours(); //Get the hour (0-23)
d.getMinutes(); //Get the minute (0-59)
d.getSeconds(); //Get the second (0-59)
d.getMilliseconds() //Get the millisecond (0-999)
d.getTime(); //Get the time (milliseconds since January 1, 1970)
d.getDay(); //Get the weekday as a number (0-6)
d.Date.now(); //Get the time. ECMAScript 5.
d.setDate() //Set the day as a number (1-31)
d.setFullYear() //Set the year (optionally month and day)
d.setHours() //Set the hour (0-23)
d.setMilliseconds() //Set the milliseconds (0-999)
d.setMinutes() //Set the minutes (0-59)
d.setMonth() //Set the month (0-11)

d.getFullYear();//Get the year as a four digit number (yyyy)
d.getMonth();//Get the month as a number (0-11)
d.getDate();//Get the day as a number (1-31)
d.getHours();//Get the hour (0-23)
d.getMinutes();//Get the minute (0-59)
d.getSeconds();//Get the second (0-59)
d.getMilliseconds();//Get the millisecond (0-999)
d.getTime();//Get the time (milliseconds since January 1, 1970)
Example 4: javascript get date
let date = new Date(); //actual time in miliseconds
let string = date.toString();
// expected output: Wed Jul 28 1993 14:39:07 GMT+0200 (CEST)
// if you need more power: date-fns.js or moment.js
Example 5: javascript date

Example 6: js get day month year
