@stephanie.dechamplain,
Thank you for your query.
I have tried to reproduce this issue with one of my sample file having the same formula. I am afraid that issue is not reproduced and today’s date is displayed. Could you please share your sample console application, template file and program output with us for our analysis. We will try to reproduce this scenario here and provide assistance accordingly.
Workbook objWB = new Workbook(path + "Book1.xlsx");
objWB.CalculateFormula();
Console.WriteLine(objWB.Worksheets[0].Cells["A1"].Value);
var result = objWB.Worksheets[0].CalculateFormula("=TEXT((INT(NOW()+0.5)),\"m/d/yyyy\")");
Console.WriteLine(result);
