Not only mind bender, it is also started giving me headache; I have tried though, and reached to the conclusion(not sure if it is correct)
(also, not sure how to explain, but here goes.)
When the day after tomorrow is yesterday,
meaning, there will be only 4 days : Y ; T ; Tom ; DAF
then today will be as far from Wednesday as today was from Wednesday
when the day before yesterday was tomorrow.
meaning, there will be only 3 days : Y ; T ; Tom
that means today has to be "Wednesday"
