Yesterday is 3 days from $Saturday$ , so today is 4 days from $Saturdays$ So 4 more days from $Saturday$ is: $Saturday~\xrightarrow[]{1 day}~Sunday~\xrightarrow[]{1 day}~Monday~\xrightarrow[]{1 day}~Tuesday~\xrightarrow[]{1 day}~Wednesday$ Because there is only 1 choice which have option $Wednesday$ so the answer is $\boxed{April~\boldsymbol{29^{th}},~Wednesday}$

That's not the complete argumentation. Today could also be Thursday with that reasoning.

Though I supposed that we may have to argue the semantics & grammar of the language part of it to reach the right mathematical answer here.
