The day Tuesday comes after Monday. The day Tuesday comes after Monday.
A day before Tuesday is Monday. A day after Tuesday is Wednesday.
Monday.
Monday
Um... No... It's a day... That comes after Monday...
there isn't one
Monday follows Sunday.
After Monday is Tuesday.
Tuesday is the day after Monday You weirdo
Tuesday
It is the next Monday.
My reasoning is thus: If as in the question - Yesterdaywas Saturday then: Today would be Sunday so 'the day after tomorow' would be: Tuesday - -(tomorrow being Monday) and: Friday comes 4 days before Tuesday (on the 7 day loop.....Friday...Saturday...Sunday...Monday...Tuesday......and so on in a loop)
