date js yyyy-mm-dd code example

Example 1: javascript date today dd mm yyyy

var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0!
var yyyy = today.getFullYear();

today = mm + '/' + dd + '/' + yyyy;
document.write(today);

Example 2: javascript convert date to yyyy-mm-dd

// `date` is a `Date` object
const formatYmd = date => date.toISOString().slice(0, 10);

// Example
formatYmd(new Date());      // 2020-05-06

Example 3: js date format yyyy-mm-dd

yourDate.toISOString().split('T')[0]

Example 4: java script print date in YYYY-MM-DD HH:MM:SS format

let date_ob = new Date();

// adjust 0 before single digit date
let date = ("0" + date_ob.getDate()).slice(-2);

// current month
let month = ("0" + (date_ob.getMonth() + 1)).slice(-2);

// current year
let year = date_ob.getFullYear();

// current hours
let hours = date_ob.getHours();

// current minutes
let minutes = date_ob.getMinutes();

// current seconds
let seconds = date_ob.getSeconds();

// prints date & time in YYYY-MM-DD HH:MM:SS format
console.log(year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds);

Example 5: javascript format date yyyy-mm-dd to dd-mm-yyyy

dateString = '2020-04-03 20:30:55';

function formatDate(dateString)
    {
        var allDate = dateString.split(' ');
        var thisDate = allDate[0].split('-');
        var thisTime = allDate[1].split(':');
        var newDate = [thisDate[2],thisDate[1],thisDate[0] ].join("-");

        var suffix = thisTime[0] >= 12 ? "PM":"AM";
        var hour = thisTime[0] > 12 ? thisTime[0] - 12 : thisTime[0];
        var hour =hour < 10 ? "0" + hour : hour;
        var min = thisTime[1] ;
        var sec = thisTime[2] ;
        var newTime = hour + ':' + min + suffix;

        return newDate + ' ' + newTime;
    }
