Calendar reasoning – If the day before yesterday was Thursday, what day will be four days after tomorrow?

Introduction / Context:
Another chained-offset problem. We will again introduce an anchor “today = T,” express each phrase in offsets, and then compute the requested weekday carefully.

Given Data / Assumptions:

• T − 2 = Thursday (day before yesterday).
• Tomorrow = T + 1.
• Four days after tomorrow = (T + 1) + 4 = T + 5.

Concept / Approach:
From T − 2 = Thursday, find T; then evaluate T + 5. Counting forward on a 7-day cycle gives the result.

Step-by-Step Solution:

Verification / Alternative check:
Compute via tomorrow first: Tomorrow is Sunday; four days after that is Thursday—identical outcome.

Why Other Options Are Wrong:

• Monday/Sunday/Wednesday: Each is off by one or more days compared with the T + 5 computation.
• None of these: A correct choice (Thursday) exists.

Common Pitfalls:
Forgetting that “day before yesterday” moves two days back, not one; or miscounting the +5 from today rather than +4 from tomorrow. Always reduce to a single offset from T.

Final Answer:
Thursday
