How can I use `javascript` to convert UTC to local time when receiving a datetime string from the server?

I’ve worked on SaaS products for global audiences, and when things got timezone-heavy, I knew I had to step it up.

Answer 3: Using Luxon for Precise Control When native JS falls short for more complex scenarios, like handling daylight savings or custom time zones, I reach for Luxon. It makes javascript convert utc to local time far more reliable:

// Include Luxon via CDN or npm
const { DateTime } = luxon;

const utcDateStr = "6/29/2011 4:52:48 PM";
const local = DateTime.fromFormat(utcDateStr, "M/d/yyyy h:mm:ss a", { zone: "utc" }).setZone("local");
console.log(local.toString());

This was a lifesaver in one of my enterprise dashboards, where customers across continents needed precision. Less guesswork, more clarity.
