In the example shown, the formula in C5 is: For example, DATE returns April 9, 2016 with the following arguments: There is no 100th day in January, so DATE simple moves forward 100 days from January 1 and figures returns the correct date. The formula on this page takes advantage of this behavior. The year assumed to be 2015 in this case, so 2015 is hard-coded for year, and 1 is used for month. The day value comes from column B, and the DATE function calculates the date as explained above.

Extracting a year value from a Julian date

If you have a date in a Julian format, for example, 10015, where the format is “dddyy”, you can adapt the formula as follows: Here, we use RIGHT to extract the 2 characters from the right for year, and LEFT to extract 3 characters from the left for day. Month is supplied as 1, like the first example.
