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 éN)i«Ù$iaß$éi¶ipiké éé)i‚$-iÌ-c@óeZdZdZdS)Ú XLDateErrorz-A base class for all datetime-related errors.N©Ú__name__Ú __module__Ú __qualname__Ú__doc__©r r ú>/var/www/html/venv/lib/python3.10/site-packages/xlrd/xldate.pyr#órc@r)ÚXLDateNegativez``xldate < 0.00``Nrr r r rr'rrc@r)ÚXLDateAmbiguouszGThe 1900 leap-year problem ``(datemode == 0 and 1.0 <= xldate < 61.0)``Nrr r r rr+rrc@r)ÚXLDateTooLargezGregorian year 10000 or laterNrr r r rr/rrc@r)ÚXLDateBadDatemodez#``datemode`` arg is neither 0 nor 1Nrr r r rr3rrc@s eZdZdS)ÚXLDateBadTupleN)r r r r r r rr7src Cs†|dvrt|ƒ‚|dkrdS|dkrt|ƒ‚t|ƒ}||}tt|dƒƒ}d|kr1dks4J‚J‚|dkrCd}}}|d7}nt|dƒ\}}t|dƒ\}}|t|kr[t|ƒ‚|dkrgddd|||fS|d krs|dkrst|ƒ‚|t|} | d d d d d | dd d } | dd dd} | ddd} | dL} | dkrµ| dd| d| |||fS| dd| d | |||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.
