so the values of our DATE arguments are: =DATE(2004,1,2) The formula in cell B3 is: =DATE(YEAR(A3),DAY(A3),MONTH(A3)) In cell B3, let's calculate the correct date for the first row (which should be 2 January 2004, but cell A3 is 1 February 2004). Then we can combine the individual pieces into a correct date, using the DATE Excel function, which takes three arguments: year, month, day – in this order – and returns a date.

Text to Columns Solutionįor those not familiar with the Text to Columns feature, let me first mention that one, because when it works, it is much faster than converting the dates using some formulas you build. This must be fixed before you can do any meaningful work with the data. Incorrect dates with reversed day and month (for rows where the original date has day 12).In sum, in the Date column you end up with two kinds of cells: Moreover, once you get to 13 January (row 10), Excel no longer treats the expressions as dates, because there is no 13th or 14th month. As a result, 2 January becomes 1 February, 5 January becomes 1 May and so on – the day and month have been reversed.
