Temporal API

Published on 26 February 2026 • Estimated reading time: 1 minutes

Dates in JavaScript are terrible. We all know this, but they’ve made big strides to prevent it from sucking anymore. So what do we get? No more weird constructor passing numbers around. Like you want now? Temporal.Now—it returns a proper prototypal object, not nonsense... and then everything gets easier.

I’m not going to explain these—you’ll just know how they work from reading. It’s that nice:

Temporal.Now.plainDateISO()

or how about:

Temporal.Now.add({days: 1})

or even:

Temporal.Now.add({days: 1}).subtract({years: 2})
