How can I subtract dates in JavaScript?

I have a field in a grid containing date/time, and I need to determine the difference between that date/time and the current date/time. What is the best way to achieve this?

The dates are stored in the format “2011-02-07 15:13:06”.

Hi,

You can convert the date string to a Date object and then subtract it from the current date to get the difference in milliseconds:

function getDateDifference(dateString) {
    // Convert the date string to a Date object
    const pastDate = new Date(dateString);
    const currentDate = new Date();

    // Calculate the difference in milliseconds
    const difference = currentDate - pastDate; // milliseconds

    // Convert milliseconds to days
    const daysDifference = Math.floor(difference / (1000 * 60 * 60 * 24));

    return daysDifference; // Return the difference in days
}

const dateStr = "2011-02-07 15:13:06";
console.log("Difference in days:", getDateDifference(dateStr));
