epochal v1.2.1

Epochal

Description

Designed for handling ambiguous historical dates, epochal is a library born out of my experiments with dynamically plotting fuzzy ancient historical events on timelines. The fundamental idea behind this library is that while "December 4th, 2020" represents a specific date, "4th millennium" actually denotes an interval that starts on January 1st, 4000 BC, and ends on December 31st, 3001 BC.

Working with natural language historical intervals can be quite complex. With epochal I've taken all the work I've done in this area and packaged it into a standalone library that anyone can use.

Installation

You can install epochal via npm or yarn:

npm install --save epochal

# or

yarn add epochal

Usage

Here's how you can use epochal in your TypeScript projects:

import { epochize } from "epochal";

const [start, end] = epochize("4th millenium BC");

console.log(start);
// January 1st, 4000 BC

console.log(end);
// December 31st, 3001 BC
