    How do I convert a julian date to a regular date?

    I need the formula to convert numbers to a standard date format. Some
    examples are as follows: 16330
    22364
    19215
    19206
    24273
    17030
    24277
    20240
    27289
    21183
    26284
    27246

    Converting A Julian Date To A Standard Date

    The formula below will convert a Julian date to a standard Excel date.

    =DATE(IF(0+(LEFT(A1,2))<30,2000,1900)+LEFT(A1,2),1,RIGHT(A1,3))

    If the year digits of the Julian date are less than 30 (i.e., 00 to 29),
    the date is assumed to be a 2000 century year. If the year digits of
    the Julian date are greater than or equal to 30 (i.e., 30 to 99), the
    date is assumed to be a 1900 century year. This formula works by taking
    advantage of the fact that the DATE function can handle days beyond the
    "normal" days in a month. For example, DATE correctly computes 100-Jan-
    1999 to be 10-April-1999.

    These Julian dates must have the leading zero or zeros for years between
    2000 and 2009. For example the 123rd day of 2000 must be entered as
    00123. Format the cell as TEXT before entering the data, or enter an
    apostrophe before the Julian date -- e.g., '00123. This will prevent
    Excel from treating the Julian date as a number and suppressing the
    leading zeros.
