How to use Intl.DateTimeFormat Method In Javascript

The Intl.DateTimeFormat method can be used to format dates and calculate the difference in days between two dates. This method is particularly useful for handling locale-specific date formatting and calculations.

Example:

JavaScript
let date1 = new Date("01/16/2024");
let date2 = new Date("01/26/2024");

// Use Intl.DateTimeFormat to format dates
let dateFormatter = new Intl.DateTimeFormat('en-US');

// Calculate the number of days between two dates
let Difference_In_Days = Math.floor((date2 - date1) / (1000 * 60 * 60 * 24));

// Display the formatted dates and the difference in days
console.log(`Total number of days between dates:
${dateFormatter.format(date1)} and ${dateFormatter.format(date2)} is: 
${Difference_In_Days} days`);

Output
Total number of days between dates:
1/16/2024 and 1/26/2024 is: 10 days

Using Two different dates

Use new Date() to create two date objects, date1 and date2.Use date2.getTime() – date1.getTime() to calculate the time difference in milliseconds between the two dates.Divide the time difference by the number of milliseconds in a day (1000 * 60 * 60 * 24) to obtain the number of days....

Using One fixed date

Present date is obtained using new Date().Christmas date is set using date.getFullYear().If Christmas has passed, adjust the date to the next year.Calculate the difference in days using Math.round((christmas_day.getTime() – present_date.getTime()) / one_day).Log the result to the console with present and Christmas dates....

Using UTC timestamps
