How to check if the value of a DataGridViewCalendarColumn has been changed?

Question

I have a data grid with a calendar column. What I want to do is an event (not sure which one is suitable), and this is what should happen:

1. There should be a check to see if one of the row's dates were changed;
2. If the value of one row has been changed (specifically the date column - which is also the only editable column), another method will execute (let's call it Update()) - I already have the method figured out. I just don't know how to do the whole check to see if a value has been changed.

CellValueChanged doesn't work as it is triggered if anything changed on the grid, such as loading the data etc. Is there something else I can use?

Let me know if I need to add more info, I'm not quite sure how to do this.

    private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
        DataGridViewColumn column = dataGridView1.Columns[e.ColumnIndex];
        if (column.Name == "dateColumn")
        {
            UpdateStuff();
        }
    }

    private void UpdateStuff()
    {
        object myDate = dataGridView1.CurrentCell.Value;
    }
