You can create a changeable Date and Time using JavaScript Date object. JavaScript Date object will automatically hold the current date and time as its initial value. You can manipulate it easily by using different methods in Date object. The different methods in Date object I am going to use to create changeable Date and Time are as follows.
- Date(): Returns today’s date and time.
- getDate(): Returns the day of the month from a Date object from 1-31.
- getDay(): Returns the day of the week from a Date object from 1-6
- getMonth(): Returns the month from a Date object from 0-11
- getFullYear(): Returns the year, as a four-digit number from the Date object.
- getHours(): Returns the hour of a Date object from 0-23.
- getMinutes(): Returns the minutes of a Date object from 0-59
- getSeconds(): Returns the seconds of a Date object from 0-59

Do rest of the work you have to create a new Date() object and needs to use that value to get the date, month, day name and time with hours, minutes and seconds. You can create variables for the day, month and year as follows.
var now=new Date();
var today=now.getDate();
var month=now.getMonth();
var year=now.getFullYear();
var day=now.getDay();You can create variables for hours, minutes and seconds as follows.
var now=new Date();
var hours=now.getHours();
var minutes=now.getMinutes();
var seconds=now.getSeconds();After getting month and day in number format, you can change it into the name of the month and day by using the arrays as follows.
