Introduction / Context:
This question is a classic example of a lateral thinking riddle about the days of the week. In normal daily life, Thursday always comes before Friday in time sequence. The puzzle asks where Friday can come before Thursday, which sounds impossible until you realize that the riddle is not talking about time, but about the order of words in a list. This type of puzzle tests your ability to shift perspective from chronological order to alphabetical or positional order.
Given Data / Assumptions:
- The words involved are Friday and Thursday, which are names of days of the week.
- In real time, Thursday always occurs before Friday within a week.
- The riddle asks about a special place or context where Friday comes before Thursday.
- Options mention a calendar, another planet, a dictionary, and a leap year.
- We assume the riddle refers to a symbolic or written ordering rather than changing the physics of time.
Concept / Approach:
The key concept is alphabetical order. In English, words can be arranged alphabetically in reference books such as dictionaries. When arranged this way, the initial letters F and T determine the position of Friday and Thursday. F comes before T in the alphabet, so Friday will appear earlier than Thursday in an alphabetical list of words, even though in real time Thursday comes first. The riddle is guiding you to think about ordering words in a dictionary, not about the calendar sequence of days.
Step-by-Step Solution:
Step 1: Note that in normal calendars and weekly schedules, the order is Monday, Tuesday, Wednesday, Thursday, Friday, and so on.
Step 2: Recognize that this chronological order cannot be changed by a leap year or by being on a different planet, because the names of the days are still used in the same weekly sequence.
Step 3: Consider other ways of ordering words, especially alphabetical order as used in a dictionary.
Step 4: Compare the first letters of Friday and Thursday. Friday begins with F, while Thursday begins with T.
Step 5: In the English alphabet, F comes before T, so Friday will appear earlier than Thursday in any alphabetical list.
Step 6: Conclude that the place where Friday comes before Thursday is in a dictionary or alphabetical word list, not in time.
Verification / Alternative check:
As a quick verification, imagine looking up days of the week in a dictionary. They are sorted alphabetically: Friday, Monday, Saturday, Sunday, Thursday, Tuesday, Wednesday. Here, Friday clearly appears before Thursday. In a calendar, however, the order is fixed by the cycle of days and does not change in this way. This confirms that In a dictionary is the expected answer to the riddle.
Why Other Options Are Wrong:
In a calendar: Calendars follow the chronological order of days; Thursday still comes before Friday in every week.
On another planet: Even if a planet has different day lengths, the naming convention of Thursday and Friday would still preserve the same order in a seven day week.
In a leap year: Leap years add a day to February but do not change the sequence of weekday names.
Common Pitfalls:
Many people initially try to imagine strange astronomical or calendar scenarios where the days could swap. This overcomplicates the problem. The riddle is simpler and focuses on word order rather than time. Whenever a question asks where one day comes before another in a surprising way, think of a dictionary or alphabetical list as the likely solution.
Final Answer:
Friday comes before Thursday
in a dictionary when the words are arranged alphabetically.
