Hi H., True, Value2 is not necessary for the Format function version, but depending on which alternative you are comparing it to, it is faster, more predictable, or both.
with the options: CELL CELL.Value CELL.Value2 CELL.Text . * CELL is a Range object, so if you use it in the context of a value, you are implicitly asking for the default property of the range, which is for most practical purposes the same as the Value property. Always best to be explicit, though (especially because there are times when the Range might be used when you want the Value and vice-versa) * CELL.Value is the value of the cell, converted to a similar VBA datatype based on the contents of the cell and the way the cell is formatted. The problems with this are: 1) this takes time, and you often don't need this to occur, 2) the VBA datatypes do not hold exactly the same information, so there is a loss of data. For example, the VBA Date datatype is lower resolution for times (while supporting a wider range of dates) than date/times on the worksheet. The VBA Currency data type is not a floating point number, but a scaled decimal, which is it's strength (no rounding errors) -- but currencies on the worksheet are floating point numbers. VBA Currency stores 4 digits afte the decimal place; floating point numbers on the worksheet store slightly over 15 significant digits (either side of the decimal). * CELL.Value2 provides the exact underlying value of cells. It's the only way to preserve those values in VBA, and it's faster than CELL.Value. Value2 is always my first choice. I fall back to Value when I require the datatype conversion that Value does. * CELL.Text is a texual representation of the cell's data as formatted on the worksheet. This often results in a loss of underlying data. Unless you need a formatted string, it requires conversion back to an appropriate datatype (whether you do it explicitly or allow VBA to do it implicitly), and CELL.Text returns "" for hidden columns.

Thanks Asa and belatedly Noorain. The format function worked and as it happens the other method was returning the wrong day for all those who might use it. The .value2 does not seem to be necessary but I left it anyway. On Wednesday, June 27, 2012 10:09:16 PM UTC-7, tangledweb wrote: Asa! Good to hear from you. I am fine. Hope the same for you. The example I posted seemed to work but I admit I did not check to see if the correct day was returned. Tomorrow I will do that and try out your format function version (which I think someone else posted earlier but I had not tried it yet).
