JavaScript Program for Converting given Time to Words

Last Updated : 13 Sep, 2023

This article will show you how to convert the given time into words in JavaScript. The given time will be in 12-hour format (hh: mm), where 0 < hh < 12, and 0 <= mm < 60.

Examples:

Input : hh = 6, mm = 20
Output : Six Hour, Twenty Minutes
Input : hh = 8, mm = 24
Output : Eight Hour, Twenty Four Minutes

Approach:

First, we create an array containing words i.e. words = [One, Two, ..., Nineteen, Twenty, Thirty, Forty, Fifty].
To convert hours into words, we get words from the array at index hours - 1, i.e. words = [hours - 1].
Check if the minutes are less than 20, then get the minute words from the array at index minute - 1, i.e. words[minutes - 1].
If minutes are greater than or equal to 20, then we get the word at index words[(17 + Math.floor(mm / 10))] and words[(mm % 10) - 1].
At last, print the value on the console.

Example: Below is the implementation of the approach

JavaScript

// JavaScript Program to Convert Given Time into Words
function printWords(hh, mm) {
    let words = [
        "One", "Two", "Three", "Four", "Five",
        "Six", "Seven", "Eight", "Nine", "Ten",
        "Eleven", "Twelve", "Thirteen",
        "Fourteen", "Fifteen", "Sixteen",
        "Seventeen", "Eighteen", "Nineteen",
        "Twenty", "Thirty", "Fourty", "Fifty"
    ];

    let minutes;

    if (mm < 20) {
        minutes = words[mm - 1];
    } else {
        minutes = words[(17 + Math.floor(mm / 10))]
            + " " + words[(mm % 10) - 1];
    }

    console.log(words[hh - 1] + " Hours, "
        + minutes + " Minutes");
}

let hh = 07;
let mm = 22;
printWords(hh, mm);

Output

Seven Hours, Twenty Two Minutes
