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
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
