In Javascript Validation Method:
var AddedOn = $("#txtAddedOn").val();
var ValidUpTo = $("#txtValidUpTo").val();

if(Date.parse(AddedOn) > Date.parse(ValidUpTo)){
   alert("ValidUpTo Should be greater then AddedOn");
}
else{
   alert("Valid date Range");
}
In Code behind/Server Side C#:
DateTime AddedOn = Convert.ToDateTime(txtAddedOn.Text.Trim());
DateTime ValidUpTo = Convert.ToDateTime(txtValidUpTo.Text.Trim());
if (ValidUpTo > AddedOn)
{
    // Doyour stuff.
}
else
{
    ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('ValidUpTo date should be greate than AddedOn date')", true);
}

You can achive through multiple ways:
On Page_Load
protected void Page_Load(object sender, EventArgs e)
{
    txtAddedOn.Text = DateTime.Now.Date;
    txtValidUpTo.Text = DateTime.Now.Date.AddDays(1);
}
Through JQuery:
$(document).ready( function() {
    const today = new Date();
    var validUpToDays = 3;
    today.setDate(today.getDate() + validUpToDays);

    $('#txtAddedOn').val(today);
    $('#txtValidUpTo').val(today);
});
Through Javascript:
const today = new Date();
var validUpToDays = 3;
today.setDate(today.getDate() + validUpToDays);

document.getElementById('txtAddedOn').value = today;
document.getElementById('txtValidUpTo').value = today;
