Javascript - How to use moment.js to add days, excluding weekends?

You can use Moment.js along with JavaScript to add days to a date while excluding weekends (Saturdays and Sundays). Here's how you can do it:

// Import Moment.js library const moment = require('moment'); // Function to add business days to a date function addBusinessDays(startDate, daysToAdd) { const resultDate = moment(startDate); let remainingDays = daysToAdd; // Loop through each day to be added while (remainingDays > 0) { // Add one day to the result date resultDate.add(1, 'days'); // Check if the result date is a weekend (Saturday or Sunday) if (resultDate.day() !== 0 && resultDate.day() !== 6) { // If it's not a weekend, decrement remaining days remainingDays--; } } return resultDate; } // Example usage: const startDate = moment('2022-05-11'); // Start date const daysToAdd = 5; // Number of business days to add const resultDate = addBusinessDays(startDate, daysToAdd); console.log(resultDate.format('YYYY-MM-DD')); // Output: 2022-05-18 (assuming no holidays)

In this code:

  • We define a function addBusinessDays(startDate, daysToAdd) that takes a start date and the number of business days to add.
  • Inside the function, we use a while loop to iterate through each day to be added.
  • We add one day to the result date (resultDate) in each iteration.
  • We check if the result date is a weekend (Saturday or Sunday) using resultDate.day().
  • If the result date is not a weekend, we decrement the remainingDays counter.
  • The loop continues until the desired number of business days is added.
  • Finally, we return the resulting date.

You can adjust the start date and the number of business days to add according to your requirements.

Examples

  1. Moment.js add business days excluding weekends

    Description: This query is about using Moment.js to add a specific number of business days to a date while excluding weekends.

    // JavaScript using Moment.js to add business days excluding weekends function addBusinessDays(startDate, daysToAdd) { var currentDate = moment(startDate); var count = 0; while (count < daysToAdd) { currentDate.add(1, 'days'); if (currentDate.day() !== 0 && currentDate.day() !== 6) { // Exclude weekends (Sunday: 0, Saturday: 6) count++; } } return currentDate.format('YYYY-MM-DD'); } // Usage example: addBusinessDays('2024-05-15', 5);

    This code defines a function addBusinessDays() that takes a start date and the number of business days to add. It iterates through each day, excluding weekends (Sunday and Saturday), until the desired number of business days is reached. Finally, it returns the result in the format 'YYYY-MM-DD'.

  2. Moment.js add weekdays excluding weekends
