📝 Steps to Solve
- Check the calendar displayed on the screen and look for the part that says "May" (e.g., the 'May' display at the top of the calendar).

- The month display on the calendar might be switched by swiping. Try moving the 'May' part.

- Remember how many days there are in June on a real calendar. The 31st does not actually exist.
🧠 Explanation & Points
This puzzle is a trick question that uses the real-world knowledge that “there is no 31st in June.” At first glance, it appears to be just a calendar screen, but the key point is that the month display is set to May. It looks like a regular calendar, but by 'swiping the May part to change it to June,' a contradiction arises between the date and the real calendar. As June does not actually have a 31st, the oddity of having a '31st in the June display' becomes the condition for the correct answer. Many players tend to first tap the 31st or look for other hidden buttons, but the key to the answer lies in combining 'changing the month' with 'knowledge of calendars'.
🔍 Common Mistakes
- Tapping '31' while it's still May (just a date tap, nothing happens, it's incorrect).
- Tapping outside the calendar (background or other buttons) trying to find hidden buttons.
- Trying to move the calendar by swiping or long pressing on dates instead of the month.
- After switching to June, tapping on dates like 30 instead of the non-existent 31.
- Forgetting there is no 31st in June and getting stuck not understanding why the change to June is necessary.
🎉 Advice After Clearing
After clearing, you can reconfirm the trivia that "there is no 31st in June" and learn that in calendar-based puzzles, 'changing the month' can often be an important mechanism. In future stages, by being mindful not to take the displayed information at face value and considering 'Is there anything that can be changed?
