Subtract days, months, years from a date in JavaScript

Question

Does anybody know of a simple way of taking a date (e.g. Today) and going back X days, X months and X years?

I have tried that:

var date = new Date()         


        

Answer 1

Use the moment.js library for time and date management.

import moment = require('moment');

const now = moment();

now.subtract(7, 'seconds'); // 7 seconds ago
now.subtract(7, 'days');    // 7 days and 7 seconds ago
now.subtract(7, 'months');  // 7 months, 7 days and 7 seconds ago
now.subtract(7, 'years');   // 7 years, 7 months, 7 days and 7 seconds ago
// because `now` has been mutated, it no longer represents the current time
