could this be any more compact or ruby like that it is?

class Date

def _financial\_year\_end_  
Date.civil(year, 6, 30) \< self ? Date.civil(year, 6, 30) :  
Date.civil(year - 1, 6, 30)  
end

end

Well, you could avoid the multiple date creations and step the date  
back 12 months when needed.

class Date  
def financial\_year\_end  
if (this\_year = Date.civil(year, 6, 30)) \< self  
this\_year  
else  
this\_year \<\< 12  
end  
end  
end

irb\> jun15 = Date.civil(2008, 6, 15)  
=\> #\<Date: 4909265/2,0,2299161\>  
irb\> jul15 = Date.civil(2008, 7, 15)  
=\> #\<Date: 4909325/2,0,2299161\>  
irb\> puts jun15  
2008-06-15  
=\> nil  
irb\> puts jul15  
2008-07-15  
=\> nil  
irb\> puts jun15, jun15.financial\_year\_end  
2008-06-15  
2007-06-30  
=\> nil  
irb\> puts jul15, jul15.financial\_year\_end  
2008-07-15  
2008-06-30  
=\> nil

The name seems odd to me as the expectation that _I_ had was to ask a  
date when the financial year that it is part of will end. However,  
it’s your method, so just document what you mean it to be.

thanks - I like the “this\_year \<\< 12” - didn’t realize this was  
available  
for dates
