If the day before yesterday was Tuesday, what day will the day after tomorrow…

In day-of-the-week reasoning, ‘the day before yesterday’ is two days before today, and ‘the day after tomorrow’ is two days after today, so the two reference points are always four days apart, with the later one ahead.

1. Day before yesterday = Tuesday.

2. So yesterday = Wednesday (one day after Tuesday).

3. Today = Thursday (one day after Wednesday).

4. Tomorrow = Friday (one day after Thursday).

5. Day after tomorrow = Saturday (one day after Friday).

Cross-check: the day before yesterday and the day after tomorrow are always four days apart. Counting four days forward from Tuesday (Wednesday, Thursday, Friday, Saturday) also gives Saturday, confirming the step-by-step result.

Hence, the day after tomorrow is Saturday.
