Usage

// Import the package
const HolidayCalendar = require('holiday-calendar');

// Create an instance
const calendar = new HolidayCalendar();

// Get index information
calendar.getIndex().then(index => {
  console.log('Supported regions:', index.regions);
});

// Get date info for a specific date
calendar.getDateInfo('CN', '2026-01-01').then(dateInfo => {
  if (dateInfo) {
    console.log(`${dateInfo.date} is ${dateInfo.name_en}`);
  }
});

// Get all dates for a specific year
calendar.getDates('CN', 2026).then(dates => {
  console.log('2026 Dates:', dates);
});

// Get dates with filters
calendar.getDates('CN', 2026, {
  type: 'public_holiday',           // Filter by type: 'public_holiday' or 'transfer_workday'
  startDate: '2026-01-01',         // Filter by start date
  endDate: '2026-12-31'           // Filter by end date
}).then(dates => {
  console.log('Filtered dates:', dates);
});

// Check if date is a workday: includes 1) Mon-Fri except public holidays, 2) transfer working weekends
calendar.isWorkday('CN', '2026-01-01').then(isWorkday => {
  console.log('Is workday:', isWorkday); // false (New Year's Day holiday)
});

// Check if date is a holiday: includes 1) public holidays, 2) weekends except transfer workdays
calendar.isHoliday('CN', '2026-01-04').then(isHoliday => {
  console.log('Is holiday:', isHoliday); // false (New Year's Day workday)
});
