About this exercise

Find the earliest 45-minute slot on Wednesday Nov 13 that fits all three people's working hours and blackouts. Reply in plain text with exactly 4 lines: Slot (New York time), then one line each showing the local time for London and Singapore, then Why: one sentence naming the constraint that ruled out earlier times. Use the rules in the notes. In November New York is 5 hours behind London and 13 hours behind Singapore.

Common mistakes when you ask AI for this

  • Wrong time zone math. The AI adds instead of subtracts. Try: Say: "London = New York + 5; Singapore = New York + 13."
  • Ignoring a blackout. The AI picks 10:30 New York. Try: Say: "Respect every blackout and lunch."
  • Wrong format. The AI writes a paragraph. Try: Say: "Exactly 4 lines."
  • Vague reason. The AI gives a generic reason. Try: Say: "Why: name the constraint that ruled out earlier times."
  • Markdown. The AI uses a table. Try: Say: "Plain text."
  • Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each line: "each line under 20 words."
  • Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each part instead, for example: "each line under 12 words."
