Converting lengthy timestamp for year extraction in TypeScript

I am facing a challenge with extracting the year from a date of birth value stored as a long in an object retrieved from the backend. I am using Angular 4 (TypeScript) for the frontend and I would like to convert this long value into a Date object in order to calculate the age. However, I am unsure about how to accomplish this parsing in TypeScript. Can anyone provide guidance on where to find relevant information?

Perhaps something similar to:

a: Number;
let a = new Date(762861060).getFullYear();

Thank you in advance for your assistance.

Answer №1

Just a small adjustment, if you're okay with whole years:

let birthDate = new Date(762861060);
let currentDate = new Date();  
let ageInYears = currentDate.getFullYear() - birthDate.getFullYear();

Answer №2

Here is a simple code snippet for calculating age:

var birthDate = new Date(762861060);
var todayDate = new Date();    
var milliDay = 1000 * 60 * 60 * 24; // represents a day in milliseconds;

var ageInDays = (todayDate - birthDate) / milliDay;   
var ageInYears =  Math.floor(ageInDays / 365 );

console.log(ageInYears)

Answer №3

If you're looking to calculate age in days and years, Moment.js is a great tool:

import * as moment from 'moment';

var difference = moment.duration((moment(762861060)).diff(moment()));
var ageInDays = difference.days();
var ageInYears = difference.years();
