The conversion from ``days`` to ``(year, month, day)`` starts with an integral "julian day number" aka JDN. FWIW: - JDN 0 corresponds to noon on Monday November 24 in Gregorian year -4713. More importantly: - Noon on Gregorian 1900-03-01 (day 61 in the 1900-based system) is JDN 2415080.0 - Noon on Gregorian 1904-01-02 (day 1 in the 1904-based system) is JDN 2416482.0 N)i$ia$iipik )i$-i-ceZdZdZy) XLDateErrorz-A base class for all datetime-related errors.N__name__ __module__ __qualname____doc__B/var/www/html/acx/venv/lib/python3.12/site-packages/xlrd/xldate.pyrr#s3rrceZdZdZy)XLDateNegativez``xldate < 0.00``Nr rrrrr'srrceZdZdZy)XLDateAmbiguouszGThe 1900 leap-year problem ``(datemode == 0 and 1.0 <= xldate < 61.0)``Nr rrrrr+sMrrceZdZdZy)XLDateTooLargezGregorian year 10000 or laterNr rrrrr/s#rrceZdZdZy)XLDateBadDatemodez#``datemode`` arg is neither 0 nor 1Nr rrrrr3s)rrc eZdZy)XLDateBadTupleN)r r r rrrrr7srrcf|dvr t||dk(ry|dkr t|t|}||z }tt|dz}d|cxkrdksJJ|dk(r dx}x}}|dz }nt |d\}}t |d\}}|t |k\r t ||dk(rddd|||fS|d kr|dk(r t||t|z} | d zd zd zd zd z| zdzd zd z} | dzd zdzdz} | dzdzdz} | dz} | dk\r| dzdz | dz | |||fS| dzdz | d z| |||fS)aU Convert an Excel number (presumed to represent a date, a datetime or a time) into a tuple suitable for feeding to datetime or mx.DateTime constructors. :param xldate: The Excel number :param datemode: 0: 1900-based, 1: 1904-based. :raises xlrd.xldate.XLDateNegative: :raises xlrd.xldate.XLDateAmbiguous: :raises xlrd.xldate.XLDateTooLarge: :raises xlrd.xldate.XLDateBadDatemode: :raises xlrd.xldate.XLDateError: :returns: Gregorian ``(year, month, day, hour, minute, nearest_second)``. .. warning:: When using this function to interpret the contents of a workbook, you should pass in the :attr:`~xlrd.book.Book.datemode` attribute of that workbook.
