Layered relative days — “The day before the day before yesterday is three days after Saturday.” What day is it today?

Introduction / Context:
These puzzles require carefully translating layered phrases into offsets from today. “Yesterday” is T − 1; “day before yesterday” is T − 2; “the day before the day before yesterday” is T − 3. Equate this to the named weekday + offset, and solve for today T.

Given Data / Assumptions:

• T denotes today.
• T − 3 equals “three days after Saturday.”
• Three days after Saturday is Tuesday (Sun = +1, Mon = +2, Tue = +3).

Concept / Approach:
Set up the identity T − 3 = Tuesday. Then add 3 days to both sides to find T. This keeps orientation consistent and avoids miscounting.

Step-by-Step Solution:
“Three days after Saturday” = Tuesday.T − 3 = Tuesday ⇒ T = Tuesday + 3 = Friday.

Verification / Alternative check:
Check the phrasing backwards from Friday: Day before day before yesterday (T − 3) is Tuesday; indeed three days after Saturday, as stated.

Why Other Options Are Wrong:
Tuesday, Wednesday, Thursday are off by −3, −2, or −1 relative to Friday when mapped through the statement.

Common Pitfalls:
Confusing “before” counts (moving backward) with “after” counts (moving forward) and swapping signs mid-calculation.

Final Answer:
Friday
