[#]_\n\nAll arguments are required. Arguments must be integers, in the following ranges\n\nMINYEAR <= year <= MAXYEAR 1 <= month <= 12 1 <= day <= number of days in the given month and year\n\nIf an argument outside those ranges is given, ValueError is raised.\n\nOther constructors, all class methods\n\nReturn the current local date.\n\nThis is equivalent to date.fromtimestamp(time.time()).\n\nReturn the local date corresponding to the POSIX timestamp, such as is returned by time.time.\n\nThis may raise OverflowError, if the timestamp is out of the range of values supported by the platform C localtime function, and OSError on localtime failure. It's common for this to be restricted to years from 1970 through 2038. Note that on non-POSIX systems that include leap seconds in their notion of a timestamp, leap seconds are ignored by fromtimestamp.\n\nReturn the date corresponding to the proleptic Gregorian ordinal, where January 1 of year 1 has ordinal 1.\n\nValueError is raised unless 1 <= ordinal <= date.max.toordinal(). For any date d, date.fromordinal(d.toordinal()) == d.\n\nReturn a date corresponding to a date_string given in any valid ISO 8601 format, with the following exceptions\n\nReduced precision dates are not currently supported (YYYY-MM, YYYY). Extended date representations are not currently supported (±YYYYYY-MM-DD). Ordinal dates are not currently supported (YYYY-OOO).\n\nReturn a date corresponding to the ISO calendar date specified by year, week and day. This is the inverse of the function date.isocalendar.\n\nReturn a .date corresponding to date_string, parsed according to format. This is equivalent to\n\nValueError is raised if the date_string and format can't be parsed by time.strptime or if it returns a value which isn't a time tuple. See also strftime-strptime-behavior and date.fromisoformat.\n\nThe earliest representable date, date(MINYEAR, 1, 1).\n\nThe latest representable date, date(MAXYEAR, 12, 31).\n\nThe smallest possible difference between non-equal date objects, timedelta(days=1).\n\nInstance attributes (read-only)\n\nBetween MINYEAR and MAXYEAR inclusive.\n\nBetween 1 and 12 inclusive. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
