Round a Date() to the nearest 5 minutes in javascript

Question

Using a Date() instance, how might I round a time to the nearest five minutes?

For example: if it\'s 4:47 p.m. it\'ll set the time to 4:45 p.m.

Answer 1

There is an NPM package @qc/date-round that can be used. Given that you have a Date instance to be rounded

import { round } from '@qc/date-round'

const dateIn = ...; // The date to be rounded
const interval = 5 * 60 * 1000; // 5 minutes
const dateOut = round(dateIn, interval)

Then you can use date-fns to format the date

import format from 'date-fns/format';

console.log(format(dateOut, 'HH:mm')) // 24-hr
console.log(format(dateOut, 'hh:mm a')) // 12-hr
