Example 1:
// Node.js program to demonstrate the
// Date.subtract() method
// Importing date-and-time module
const date = require('date-and-time')
// Creating object of current date and time
// by using Date()
const now = new Date();
// Creating object of given date and time
const date1 = new Date(2015, 0, 1);
// Subtracting the both dates
// by using date.subtract() method
const value = date.subtract(now,date1);
// Display the result
console.log("total days between them "
+ value.toDays())
Run the index.js file using the following command:
node index.js
Output:
total days between them 2270.3951833333335
Example 2:
// Node.js program to demonstrate the
// Date.subtract() method
// Importing date-and-time module
const date = require('date-and-time')
// Creating object of current date and time
// by using Date()
const now = new Date();
// Setting days in the existing date
now.setDate(20);
// Creating object of given date and time
const date1 = new Date(2015, 0, 1);
// Subtracting the both dates
// by using date.subtract() method
const value = date.subtract(now,date1);
// Display the result
console.log("total days between them " + value.toDays())
Run the index.js file using the following command:
node index.js
Output:
total days between them 2270.397227997685
