 * @module natural-time-js
 * @description Natural time is a fresh, elegant, and coherent way of measuring the movements of time here on the Earth.
 * This new time standard is based on common sense and the observation of natural cycles.
 * Our current Gregorian calendar is an artificial construct disconnected from natural cycles.
 * Natural time realigns us with the observable patterns of the cosmos:
 * It's time to return to the cosmic rhythms that have guided humanity for millennia.

 * # Natural Time JavaScript Library
 *
 * This JavaScript library translates Gregorian (artificial) datetime to natural datetime.
 * Natural time is defined by:
 *
 * - 360° circular time - replacing arbitrary hours with continuous movement
 * - Make the sun back as the main source of time
 * - Years beginning at the winter solstice
 * - 13 perfect moons of 28 days = 364 days
 * - "Rainbow day(s)" - Day out of time to make the year 365 or 366 days
 *
 * This is mathematical beauty aligned with astronomical reality.
 *
 * ## Basic Usage
 *
 * ```typescript
 * import { NaturalDate } from 'natural-time-js';
 *
 * // Create a natural date for the current time at longitude 0
 * const naturalDate = new NaturalDate(new Date(), 0);
 *
 * // Display the natural date
 * console.log(naturalDate.toString());
 * // Example output: "011)04)15 113°25 NTZ"
 *
 * // Get specific components
 * console.log(`Year: ${naturalDate.year}`);
 * console.log(`Moon: ${naturalDate.moon}`);
 * console.log(`Day of moon: ${naturalDate.dayOfMoon}`);
 * console.log(`Time: ${naturalDate.time}°`);
 * ```
 *
 * ## Astronomical Functions
 *
 * The library provides astronomical functions for calculating sun and moon positions:
 *
 * ```typescript
 * import { NaturalDate, NaturalSunEvents, NaturalMoonPosition } from 'natural-time-js';
 *
 * const naturalDate = new NaturalDate(new Date(), 0);
 * const latitude = 45; // 45° North
 *
 * // Get sun events for the day
 * const sunEvents = NaturalSunEvents(naturalDate, latitude);
 * console.log(`Sunrise: ${sunEvents.sunrise}°`);
 * console.log(`Sunset: ${sunEvents.sunset}°`);
 *
 * // Get moon position and phase
 * const moonInfo = NaturalMoonPosition(naturalDate, latitude);
 * console.log(`Moon phase: ${moonInfo.phase}°`);
 * ```
