Tomorrow, I will die!

James and Jonathan are liars, who lie on specific days.

James lies on Fridays, Saturdays and Sundays,
but he is honest on all other days.

Jonathan lies on Tuesdays, Wednesdays and Thursdays,
but he tells the truth on all other days.

On what day of the week would they both say “Tomorrow, I will lie.”?

Scroll down for the answer.

Answer is Thursday

Lets say if the person is speaking truth then he must be lie on next day, but if he is lying while saying “Tomorrow i will lie” then he will speak truth on next day.

So they can say the statement only when they change their behavior on next day.

Lets prepare a table for James and Jonathan for all days

                  James                                            Jonathan
Monday   Truth                                            Truth
Tuesday   Truth                                             Lie
Wed.   Truth                                             Lie
Thursday   Truth                                             Lie
Friday    Lie                                             Truth
Saturday    Lie                                             Truth
Sunday    Lie                                             Truth

From above table

James can say the statement on Thursday and Sunday

and Jonathan can say it on Monday and Thursday.

As both of them say the statement on same day, so it must be Thursday only.
