// 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

// by using date.subtract() method
const value = date.subtract(now,date1);

// Display the result
console.log("total days between them "
   + value.toDays())
