I would like to know the formula to convert a date in 10/26/2013 to 41573 number as done in Excel.
Like how 10/26/2013 is converted to 41573.
If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900
If your date is text and you need to convert it then DATEVALUE
will do this:
