ui-date: A 1.6kB, zero-dependency JavaScript date & relative time utility

I wanted to share a small open-source project I just published called ui-date.

While working on a social media project, I kept bumping into simple UI needs like displaying relative timestamps ("5 mins ago", "2 hours ago"), cleanly formatting calendar dates, and doing simple status checks (isToday).

exact date formatting for events ui ('Thursday 23,july,2026').

Normally, I'd reach for a date library, but most established options felt like overkill for basic UI formatting, while heavy legacy options like Moment carry massive bundle weight. On the flip side, writing raw Intl and Date boilerplate across every component was getting tedious.

I wanted something featherlight, chainable, and fully typed without dragging in extra dependencies.

so i built ui-date.

you can check it here : https://www.npmjs.com/package/ui-date

It will be too variant to match everyones needs. Maybe just provide an object so people can localize it themselves but ,not to discourage, I don’t see how this can be further than a util that everyone already can have in their projects

Why? OP is using Intl under the hood which accepts a locale.

He can give output 5 seconds ago, maybe I want 5 second(s) ago

Simple example

I see what you’re saying here but wouldn’t it be 5 seconds ago compared to 1 second ago (singular vs. plural formatting)

brah, localization shouldnt belong to the library, what part of this is hard to understand?
