Calendar Reasoning
Calendar reasoning questions ask for a day of the week a certain number of days before or after a known date. Because the week repeats every 7 days, only the remainder after dividing by 7 matters — leap years add one extra consideration when a full year is involved.
Common patterns
- Advancing or moving back a fixed number of days
- A full-year shift, where a leap year adds an extra day to account for
Worked example
Question: Today is Wednesday. What day will it be after 17 days?
Answer: Saturday
17 days is 2 full weeks plus 3 extra days; 3 days after Wednesday is Saturday.
