JavaScript

🟨

JavaScript ES module classes exported under a single Timely namespace.

📦 Namespace (src/timely/index.js)

All classes are re-exported from index.js, so they can be imported as one namespace object:

import * as Timely from "./src/timely/index.js";

Timely.Helper.isLeap(2000);          // true
Timely.Calculator.sundayOudin(2014);     // Date of Easter Sunday

Named imports work as well:

import {Helper, Calculator} from "./src/timely/index.js";

When the package is installed from npm, the entry point is defined by exports in package.json:

import * as Timely from "@hermajan/timely";

🧩 Classes

Class	File	Static methods
YearHelper	years/Helper.js	isLeap(year), isLeap2(year)
DateFormatter	dates/DateUtil.js	dayOfWeek(lang, date), formatDate(date)
Week	dates/Week.js	cs, en (names of the days of the week)
EasterCalculator	easter/Calculator.js	sundayOudin(year), friday(year), monday(year)
CzechNameDayFinder	namedays/czech/CzechFinder.js	nameDay(day, month), todayName(), getName(date)
SlovakNameDayFinder	namedays/slovak/SlovakFinder.js	the same as CzechNameDayFinder

The clocks in clocks/ are still plain scripts and are not part of the namespace.

🌐 Usage in a browser

Use a module script. Module scripts are deferred, so do not use document.write(); fill elements instead:

<span id="today"></span>
<script type="module">
	import * as Timely from "./src/timely/index.js";
	
	document.getElementById("today").textContent = Timely.DateUtil.dmy();
</script>

Working demos are in the Examples.

Browsers do not load modules from file://, so serve the project through a local web server (e.g. npx serve or python -m http.server).
