iq question

W hat day is it today? if "The day before the day before yesterday is 3 days after Saturday, = "The day before the day before yesterday is Tuesday"
1) hence ...yesterday is Tuesday. =...Wednesday hence "The day before the day before Wednesday "but ...the day before Wednesday = Tuesday hence "The day before Tuesday" = Monday.
2) OR ...the day before yesterday= 2 days ago hence  'The day before 2 days ago is Tuesday " hence ...2 days ago is Tuesday =Thursday hence "The day before Thursday"  = Wednesday
3) OR The day before...=yesterday=1 day previous hence "Yesterday yesterday yesterday is Tuesday" = "3 days previous is Tuesday" =Friday (correct answer me thinks)
It appears if one takes out "is" ( shan't it have read, "The day before the day before yesterday WAS three days after Saturday. what day is it today?") the answer changes.  eg. from 1) ...the day before Wednesday = Tuesday is true BUT ...the day before "was/is" Wednesday=Tuesday is false.
So 1) changes to "The day before the day before was Wednesday " and  "...the day before was Wednesday =was Thursday hence "The day before was Thursday" = was Friday.
