extract days from date and time

You can't extract a number of days from a single point in time. To extract a number of days you need a start date and an end date. Read up on the DATEDIF function to see if that is what you are looking for. Click Here Before Posting Data or VBA Code ---> How To Post Data or Code.

In the example given all you need to do is change the cell's format to "General". Since, according to Excel, time began in 1/1/1900 = 1 and 9/21/1900 = 265 and 1/21/2013 = 41295. Your example will actually equate to 265.7805093. - the .7805 reflecting the time. If you want to get just the day irrespective of the time you can calculate that as =Int(A1) and, again, formt the cell as General. The question is, why do you need this?

Thanks Altek, INT formula works...
