How to format the current date in MM/DD/YYYY HH:MM:SS format using Node.js?
  • Last Updated : 17 Mar, 2021

The current date can be formatted by using the Nodejs modules like Date Object or libraries like moment.js, dayjs

Method 1: Using Node.js Date Object

The JavaScript Date Object can be used in the program by using the following command.

const date = new Date();

Now on this variable date, we can apply methods to obtain various results according to the requirement. Some methods are:

  • getDate(): The method returns the current date.
  • getMonth(): The method returns current month.
  • getFullYear(): The method returns the current year.
  • getHour(): The method returns the current hour in 24-hour format.
  • getMinutes(): The method returns minutes of the current hour.
  • getSeconds(): The method returns seconds of the current minute.

Below is the implementation of the program:



  • In the object format dd is current day, mm is month, yyyy is year, HH is hour in 24-hour format, hh is hour in 12-hour format, MM is minutes, SS is seconds.
  • The function formatData() takes an input and checks if it is greater than 9 or not. If it is greater than 10 it will return it without any change but if it is less than 10 then it will append a 0 in front of the input.
  • The function formatHour() takes hours as input and converts it according to the 12-hour clock.
  • The functions format24Hour() and format12Hour() prints the date in format MM/DD/YYYY HH:MM:SS in 24-hour and 12-hour format respectively.

index.js




const date = new Date();
  
// Function to convert
// single digit input
// to two digits
const formatData = (input) => {
  if (input > 9) {
    return input;
  } else return `0${input}`;
};
  
// Function to convert
// 24 Hour to 12 Hour clock
const formatHour = (input) => {
  if (input > 12) {
    return input - 12;
  }
  return input;
};
  
// Data about date
const format = {
  dd: formatData(date.getDate()),
  mm: formatData(date.getMonth() + 1),
  yyyy: date.getFullYear(),
  HH: formatData(date.getHours()),
  hh: formatData(formatHour(date.getHours())),
  MM: formatData(date.getMinutes()),
  SS: formatData(date.getSeconds()),
};
const format24Hour = ({ dd, mm, yyyy, HH, MM, SS }) => {
  console.log(`${mm}/${dd}/${yyyy} ${HH}:${MM}:${SS}`);
};
const format12Hour = ({ dd, mm, yyyy, hh, MM, SS }) => {
  console.log(`${mm}/${dd}/${yyyy} ${hh}:${MM}:${SS}`);
};
  
// Time in 24 Hour format
format24Hour(format);
// Time in 12 Hour format
format12Hour(format);

Run index.js file using below command:

node index.js

Output:

Method 2: Using Moment.js Library.

index.js




const moment = require("moment");
  
// 24 Hour format
console.log(moment().format("MM/DD/YYYY HH:mm:ss"));
// 12 Hour format
console.log(moment().format("MM/DD/YYYY hh:mm:ss"));

Run index.js file using below command:

node index.js

Output:
