Day before yesterday: Wednesday
Today: Friday
Day after tomorrow: Sunday

Day before yesterday is a term used to refer to the day that occurred two days before the current day. Therefore, if the day before yesterday was Wednesday, then the day before that would have been Tuesday and the day before that would have been Monday. Hence, Sunday will be the day after tomorrow.

To understand this concept better, let us look at an example.

Let us suppose that today’s date is 11th August. The day before yesterday would be 9th August (i.e. two days before 11th August). The day before that would be 8th August (i.e. three days before 11th August). Thus, Sunday would be the day after tomorrow i.e. 13th August.

Below is a summary of the concepts discussed in this solution:
•Day before yesterday is a term used to refer to the day that occurred two days before the current day.
•If the day before yesterday was Wednesday, then the day before that would have been Tuesday and the day before that would have been Monday.
•Hence, Sunday will be the day after tomorrow.
