tenth_day = proc { |d|
   d[/Julian day: (\d+)/, 1].to_i % 10 == Date.new(2004,1,8).jd % 10
}

puts "It's a multiple of ten days since 8 Jan 2004" if tenth_day[coords]


The complete output is:

"day-ordinal-month: 4, 3, 3; day-month: 18, 3; day-week: 4, 12; day of 
year: 78; Julian day: 2453083; year: 2004"
It's Thursday again.
It's the 1st or 3rd Thursday again.
It's a multiple of ten days since 8 Jan 2004
