How to use Two different dates In Javascript

Q: How to use Two different dates In Javascript

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

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.

Example: The following JavaScript program will illustrate the process of finding the number of days between two dates.

javascript

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

// Calculating the time difference
// of two dates
let Difference_In_Time =
    date2.getTime() - date1.getTime();

// Calculating the no. of days between
// two dates
let Difference_In_Days =
    Math.round
        (Difference_In_Time / (1000 * 3600 * 24));

// To display the final no. of days (result)
console.log
    ("Total number of days between dates:\n" +
        date1.toDateString() + " and " +
        date2.toDateString() +
        " is: " + Difference_In_Days + " days");

Output

Total number of days between dates:
Tue Jan 16 2024 and Fri Jan 26 2024 is: 10 days
