Workday Checker

Workday Checker is a Node.js package that allows you to check whether a given date is a workday or not, considering weekends and user-defined holidays.

Installation

To install Workday Checker, you can use npm:

npm install workday-checker

Usage

const workdayChecker = require('workday-checker');

// Set locale and update holidays
workdayChecker.update('en-US', ['2024-01-01', '2024-12-25']); // Update locale and holidays

// Check if a date is a workday
const date = new Date('2024-04-15');
const isWorkday = workdayChecker.isWorkday(date);
console.log(isWorkday); // Output: true

// Get the next workday
const nextWorkday = workdayChecker.getNextWorkday(date);
console.log(nextWorkday); // Output: 2024-04-16

// Check if a date is a holiday
const isHoliday = workdayChecker.isHoliday(date);
console.log(isHoliday); // Output: false

// Add a new holiday
workdayChecker.addHoliday('2024-05-01'); // Add May 1st as a holiday

// Remove a holiday
workdayChecker.removeHoliday('2024-12-25'); // Remove December 25th as a holiday

// Get workdays within a date range
const startDate = new Date('2024-04-01');
const endDate = new Date('2024-04-30');
const workdaysInRange = workdayChecker.getWorkdaysInRange(startDate, endDate);
console.log(workdaysInRange); // Output: Array of workdays between April 1st and April 30th

// Get the name of a holiday
const holidayName = workdayChecker.getHolidayName(date);
