There is also an approach which does not need ranges:
irb(main):001:0> d = 3.times.map {sleep 1; Time.now}
=> [2012-10-06 11:56:34 +0200, 2012-10-06 11:56:35 +0200, 2012-10-06
11:56:36 +0200]
irb(main):002:0> d[1].between? d[0], d[1]
=> true
irb(main):003:0> d[1].between? d[0], d[2]
=> true
irb(main):004:0> d[0].between? d[1], d[2]
=> false
With Date
irb(main):005:0> require 'date'
=> true
irb(main):006:0> d = 3.times.map {|i| Date.today + i}
=> [#<Date: 2012-10-06 ((2456207j,0s,0n),+0s,2299161j)>, #<Date:
2012-10-07 ((2456208j,0s,0n),+0s,2299161j)>, #<Date: 2012-10-08
((2456209j,0s,0n),+0s,2299161j)>]
irb(main):007:0> puts d
2012-10-06
2012-10-07
2012-10-08
=> nil
irb(main):008:0> d[1].between? d[0], d[2]
=> true
irb(main):009:0> d[0].between? d[1], d[1]
=> false
irb(main):010:0> d[0].between? d[0], d[1]
=> true
irb(main):011:0> d[0].between? d[1], d[2]
=> false
irb(main):012:0> d[1].between? d[0], d[1]
=> true
This is for inclusive ranges. If you want to exclude either bound
just use a date +/- 1.
Kind regards
