How to Get an Array of Dates Between Two Dates in Javascript?

Getting a Date Array between Two Dates in Javascript

Determining the array of date objects for each day between two given dates is a common task when working with dates in Javascript. This array needs to account for month and year boundaries to maintain accuracy.

Implementation:

To achieve this, we can define a function called getDates that takes two date objects as parameters: a starting date and an end date. Within this function:

1. Initialize an Array to Store Dates: Create an empty array called dateArray to store the date objects for each day.
2. Initialize Current Date: Set the currentDate variable to the starting date.
3. Iterate Through Days: Use a while loop to iterate through the days until the currentDate is greater than or equal to the end date.
4. Push Date to Array: Inside the loop, add a new Date object representing the current date to the dateArray.
5. Increment Current Date: Increment the currentDate by one day using the addDays method.
6. Return the Date Array: Once the loop finishes, return the dateArray.

Example Code:

Here's an example of how you can implement the getDates function:

Date.prototype.addDays = function(days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
}

function getDates(startDate, stopDate) {
    var dateArray = new Array();
    var currentDate = startDate;
    while (currentDate <= stopDate) {
        dateArray.push(new Date (currentDate));
        currentDate = currentDate.addDays(1);
    }
    return dateArray;
}

This implementation extends the Date prototype with an addDays method for convenience. A live demo can be found at http://jsfiddle.net/jfhartsock/cM3ZU/.
