I have a hash of data:
%highest_level = ( 2001-10-14 => 152, 2002-01-15 => 163, 2003-03-13 => 210, 2004-08-07 => 307 );
I think you mean:
%highest_level = (
'2001-10-14' => 152,
'2002-01-15' => 163,
'2003-03-13' => 210,
'2004-08-07' => 307
);because otherwise the dates will be interpreted as (eg) 2001 minus 10 minus 14 == 1977.
Bravo for using decent, civilised ISO dates and not those crazy little-endian dates (as favoured by silly Europeans) or ridiculous middle-endian dates (as favoured by silly .USians)!
And I am give some dates in between:
@dates = ( 2001-12-30, 2002-03-19);
Again, quote the dates.
Am I missing something or is this harder than it first appears?
Aside from the above you're missing the many and varied Date::* modules on CPAN which exist to make date and time handling, including comparisons like what you need, easy. I won't say which one to use cos that's a religious issue :-)
