 |  Class methods defined here:
 |  
 |  fromisocalendar(...) from builtins.type
 |      int, int, int -> Construct a date from the ISO year, week number and weekday.
 |      
 |      This is the inverse of the date.isocalendar() function
 |  
 |  fromisoformat(...) from builtins.type
 |      str -> Construct a date from the output of date.isoformat()
 |  
 |  fromordinal(...) from builtins.type
 |      int -> date corresponding to a proleptic Gregorian ordinal.
 |  
 |  fromtimestamp(timestamp, /) from builtins.type
 |      Create a date from a POSIX timestamp.
 |      
 |      The timestamp is a number, e.g. created via time.time(), that is interpreted
 |      as local time.
 |  
 |  today(...) from builtins.type
 |      Current date or datetime:  same as self.__class__.fromtimestamp(time.time()).
 |  
 |  ----------------------------------------------------------------------
 |  Static methods defined here:
 |  
 |  __new__(*args, **kwargs) from builtins.type
 |      Create and return a new object.  See help(type) for accurate signature.
