Using sheet names as a named range

Hi. I,m not sure if what I want is possible, but here goes. I have a namd sheet for everyday of the year in a workbook, so jan1 jan2 jan3 etc. I have a stats page which brings together certain pertinent data from those pages, so a formula on the stats page might look like this =sum('jan1'!$m$25:$m$900). What I would like to do is to name each day - jan1 jan2 etc as a named range perhaps date1 date2 etc so that the above formula would then look like =sum(date1!$m$25:$m$900). Is this possible to do, and if so how? Thanks for all and any help Smileyc

One way would be the use of INDIRECT

=SUM(INDIRECT(E5&"!$m$25:$m$900"))

Where the cell E5 contains the sheet name.
