Is the following correct according to the spec (note end "to" date for
the interval)?
irb(main):014:0> d = Date.edtf('1984/1985')
=> #<EDTF::Interval:0x45932c @from=#<Date: 1984-01-01
(4891401/2,0,2299161)>, @to=#<Date: 1985-01-01 (4892133/2,0,2299161)>>
irb(main):015:0> d.from.to_s
=> "1984-01-01"
irb(main):016:0> d.to.to_s
=> "1985-01-01"
