Small & sweet date-range formatting

An opinionated library that makes date-ranges short and readable.

_{Prepared by Timo Lins 👨‍🍳 for a ▲ Vercel Hackathon}

Introduction

When displaying date-ranges in UI, they are often too long and hard to read. This library tries to solve that problem.

little-date is a date-formatting library, based on date-fns. It aims to make date ranges short, readable and easy to understand.

It supports localization and can be used in both Node.js and the browser.

Examples dates ✨

• Jan 1 - 12
• Jan 3 - Apr 20
• January 2023
• Q1 2023

Wasn't that easy to read? You can find a full list of formatting examples here.

Advanced Options

Most of of the formatting behavior is opinionated and can't be changed. However, there are some options that can be used to customize the output.

import { formatDateRange } from "little-date";

// ...

formatDateRange(from, to, {
  locale: "de-AT", // Overwrite the default locale
  includeTime: false, // Prevent time from being displayed
  today: new Date(), // Overwrite the default "today" date, useful for testing
  separator: "-", // Overwrite the default separator. E.g. from "Jan 1 - 12" to "Jan 1 to 12"
});
