Vanilla JavaScript get current timestamp

dailydevtips1 profile image Chris Bongers Originally published at daily-dev-tips.com ・1 min read

Today I needed to get a timestamp to include in a unique file that I'm generating with Node.js.

It's one of these things that after 17 years, I still google to this day... Call me stupid or just ignorant in not saving it in my brain.

Getting a Timestamp in JavaScript

Date.now();
Enter fullscreen mode Exit fullscreen mode

Wow, That was the one thing I can't get in my head?!
Yes. There are other ways of doing it, so here are some alternatives that do the same:

new Date().getTime();
new Date().valueOf();
Enter fullscreen mode Exit fullscreen mode

All three methods will get a millisecond timestamp; we can convert it to seconds by doing so:

Math.floor(Date.now() / 1000);
Enter fullscreen mode Exit fullscreen mode

Feel free to have a look and play on this Codepen.
