A lies on mon, tues, wed and speak truths on other days, B lies on Thurs, Fri, Sat and speaks truths on other days. One day a said I lied today and B said I too lied today. What is the day?

• Please check the question because it leads to a paradox. The question should be "Man A lies on monday,tuesday and wednesday.Man B lies on thursday,friday
  and saturday.On one particular day A said "Yesterday i lied".then B said
  "Yesterday i lied too".On which day were these statements made?"
  Now the ans is Thursday.

• This question is either not correct or the answer will be "It can't be possible"
  
  This is because::::day can't be Sun,Mon,tue and wed acc. to B as he on this days he only speaks truth so he can't say that today i lied.
  Similary A can't say on Sun,Thrusday,fri,sat that i lied today because these day he can't lie and so he can't speak that today i lied amoung these days.
  
  So acc. to A, today can only be mon,tue and wed but acc. to b today can only be thr, fri, sat.
  
  Since there today set has null intersection (nothing common), so there can't be a any day when this situation holds true.

• sunday is the answer...because one day is common between their two's schedule to speak lies and truth and its sunday.

• both tell truth on sunday..
  here both confessed the truth that they lied on that day..
  so,it is nothing but "sunday"..

• A and B both agree
  If I was telling the truth, then both
  A and B were lying.
  ---------------
  But there is no day that both
  A and B are lying, since:
  A is lying on
  Mon, Tues, Wed
  
  B is lying on
  Thurs, Fri, Sat
  -------------
  Therefore, I must have been lying
  and both A and B were telling the truth
  -------------
  There is only 1 day when both A and B
  are telling the truth, so today
  must be Sunday
