Hi Eustus Muhanguzi,

I'm not sure if I understood your question correctly. Do you want to get this message at midnight at the transition from End_Date - 1 to End_Date?
I suggest you add a Timer that ticks every second or every couple of seconds.  Whenever it ticks, compare DateTime.ToDay to End_Date.Date. You can do this in a loop processing all rows from the DataGridView (DGV). If the End_Date is reached, you have
to remember that for this row the day has already been recognized as the birthday. You can do this in the same row or by keeping another List. After that, call MessageBox.Show to display the message.
Please let us know if the DGV is data bound or unbound.
It is not clear what happens if the program is not always running. If it is started at End_Date, midnight has already been passed.
I do not see which role the Start_date plays in this comparison.
