<<----: Date & Time in JavaScript :---->>
1. Date Methods(get and set)
2. Time Method(get and set)
JavaScript Date object represent a single moment in time in a
platform-independent format. Data onjects contain a number
that represent milli-seconds since 1 january 1970 UTC.
❄ Creating Object
There are 4 way to create a new data object:
a. new Date()
b. new Date(year,month,day,hours,minutes,seconds,milliseconds)
it takes 7 arguments
c. new Date(milliseconds)
we cannot avoid month section
new Date(date string)
👉new Date()
Date object are created with the new Data() constructer
let currDate = new Date();
console.log(currDate);
console.log(new Date());
console.log(new Date().toLocaleString()); // 9/11/2019, 1;25:01 Pm
console.log(new Date().toString()); // Wed Sep 11 2019 13:25:01
👉Date.now()
Return the numeric value corresponding to the current time-the Number
of milliseconds elapsed since january 1, 1970 00:00:00 UTC
console.log(Date.now());
👉new Date(year, month,...)
7 number specify year,month,day,hour,minutes,second and mil-sec (in that order)
Note: JavaScript counts months from 0 to 11.
januay is 0 and Dec is 11.
Month argument is must
var d = new Date(2021,7,27,20,20,0);
console.log(d.toLocaleString());
👉new Date(dateString)
new Date(dateString) creates a new object from a date string
var d = new Date("october 13, 2014 11:13:00");
console.log(d.toLocaleString());
Date Methods :-
const currDate = new Date();
How to get the invisible date.
console.log(currDate.toLocaleString())
console.log(currDate.getFullYear());
console.log(currDate.getMonth()); // 0 to 11 jan to dec
console.log(currDate.getDate());
console.log(currDate.getDay());
How to set the individual date.
console.log(currDate.setFullYear(2022));
console.log(currDate.setFullYear(2022,10,5));
console.log(currDate.setMonth(10));
console.log(currDate.setDate(5));
console.log(currDate.toLocaleString());
Time Methods :-
const curTime = new Date();
how to get the indivdual time
console.log(curTime.getTime());
// The getTime() method return the number of milliseconds
// since january 1,1970
console.log(curTime.getHours());
// The getHours() method returns the hours of a date as a
// number (0-23)
console.log(curTime.getMinutes());
console.log(curTime.getSeconds());
console.log(curTime.getMilliseconds());
How to get the invisible date.
let curTime = new Date();
console.log(curTime.setHours(5));
console.log(curTime.setMinutes(5));
console.log(curTime.setSeconds(5));
console.log(curTime.setMilliseconds(5));
Practise Time :-
new Date().toLocaleTimeString(); // 11:18:48 AM
new Date().toLocaleDateString(); // 11/16/2015
new Date().toLocaleString(); // 11/16/2015,11:18:48 PM
