console.log(
  calendar.create().output(),
);

/**
 *  Output:
 * [{
 *   year: '2023',
 *   month: 'june',
 *   monthIndex: 5,
 *   weekLabels: ['sunday', 'monday', 'tuesday', ...],
 *   dates: [2023-05-27T18:30:00.000Z, 2023-05-28T18:30:00.000Z, 2023-05-29T18:30:00.000Z, ...]
 * }]
 */

Calendar class:

Customize a calendar using Calendar class.

import { Calendar, Week } from "argon-calendar-core";
const calendar = new Calendar({
  visibleMonthCount: 1, // Show one month at a time. The default value is 1.
  visibleWeekCount: 6, // Show 6 weeks in a month. The default value is 6.
  weekStartsOn: Week.SUN, // Start the week on "sunday". The default value is "sunday".
});
console.log(
  calendar.create().output(),

/**
 *  Output:

Formatting:

The API allows to format output as per your preference. The default output contains list of dates in a raw Date format. The following example converts date to string format.

import { Calendar, Week } from "argon-calendar-core";
const calendar = new Calendar({
  visibleMonthCount: 1, // Show one month at a time
  visibleWeekCount: 6, // Show 6 weeks in a month
  weekStartsOn: Week.SUN, // Start the week on "sunday"
});
console.log(
  calendar.create().map<string>((dt) => dt.toString()),
);

/**
 *  Output:
 * [{
 *   year: '2023',
 *   month: 'june',
 *   monthIndex: 5,
 *   weekLabels: ['sunday', 'monday', 'tuesday', ...],
 *   dates: [
 *     'Sun May 28 2023 00:00:00 GMT+0530 (India Standard Time)',
 *     'Mon May 29 2023 00:00:00 GMT+0530 (India Standard Time)',
 *     'Tue May 30 2023 00:00:00 GMT+0530 (India Standard Time)',
 *     ...
 *   ]
 * }]
 */

// Assuming current month is June 2023
// ...
console.log(
  calendar.create(+1).output(),
); // Outputs month of July

console.log(
  calendar.create(+2).output(),
); // Outputs month of August

console.log(
  calendar.create(-1).output(),
); // Outputs month of May

console.log(
  calendar.create(-2).output(),
); // Outputs month of April
