Rachel and David are twins; Rachel is the OLDER twin. Assume they were born immediately after each other, an infinitesimally small - but nonzero - amount of time apart. During a year in the course of their lives, Rachel celebrates her birthday two days AFTER David does. How is this possible?
Bonus: What is the maximum amount of time by which Rachel and David can be apart in their birthday celebrations during the same year?
Note: For both Rachel and David, these birthday celebrations happen on the actual birthday date -- it cannot be a celebration that occurs at a date earlier or later than the actual birthday date for whatever reasons of convenience. Also, the solution has nothing to do with the theory of relativity or any other over complicated nonsense like that.
