# C14 · A family birthday card

Prepare a fictional birthday schedule, without a real child's details. A family wants an interesting time question on the card. Child may choose day/night turn, a longer Moon-appearance record, or about-year orbit. Worked example: use a source-qualified about-year orbit caption; birthday schedule is a calendar choice, not an exact measured orbital interval. No season-from-nearest-distance claim. Finish with one question and relevant source/time story. Next help: offer two unrelated captions and ask which explains the child's chosen purpose.
