Dup vs Clone difference

As for me main difference between .dup and .clone , that first one doesn’t not freeze result object if initial object was frozen.

To illustrate Date class let's calculate days between dates

Code example

date_from = Date.new(2010, 9, 11)
#<Date: 4910901/2,0,2299161>
date_till = Date.new(2010, 11, 12)
#<Date: 4911025/2,0,2299161>
rational_offset = (date_till - date_from)
#Rational62, 1
rational_offset.to_i
#62
