Remember that 0 in Ruby is not false, only 'nil' and false are. 0 is
the index of where in your string your match starts. Your RegEx is ok:

>> m=/\d{4}-\d{2}-\d{2}/.match(date)
=> #<MatchData:0x573348>
>> pp m
#<MatchData "2009-06-01">

Also this little change should make it obvious what happens:

>> date = "blablabla2009-06-01"
=> "blablabla2009-06-01"
>> date =~ /\d{4}-\d{2}-\d{2}$/
=> 9

HTH,
Michael
