Trying out a Jquery to confirm if date selected is equal to today or greater than. If i select today, it return it as the day selected is less than today. Selecting previous day works well but selecting today returns less than. Any tip.

var firstRepaymentDate = new Date($('#First_Repayment_Date').val());
                var today = new Date();
                if (firstRepaymentDate.getTime() < today.getTime()) {
                    alert('The First Repayment Date Can only Be Today Or Future Date');
                    return false;
                }

• new Date() will include the current time not just the date. Try today.setHours(0, 0, 0, 0) to set the time to midnight. – phuzi Commented Jan 21, 2021 at 16:11

Don't forget that new Date() will include the current time as well. You'll need to remove that time ponent with today.setHours(0,0,0,0) for the parison to be correct.

Also, setHours() returns the underlying value like getTime() so you can do

var firstRepaymentDate = new Date($('#First_Repayment_Date').val());
var today = new Date();
if (firstRepaymentDate.getTime() < today.setHours(0,0,0,0)) {
    alert('The First Repayment Date Can only Be Today Or Future Date');
    return false;
}

In response to the ment about adding 20 days:

This is a little more detailed but is fairly easy.

var today = new Date();
var plus20Days = new Date(today.setDate(today.getDate() + 20));

again you can then use setHours() to reset the time ponent.

new Date() considers time too, not only the date. I think the easiest way to achieve this is to pare years, months and days by using respectively getFullYear() , getMonth() , getDate().
