The day before yesterday, Janet was 13 years old. Next year, she’ll be 16.
What is her birthday, and what is today’s date?
Answer: Today’s date is January 1, so the day before yesterday, i.e., on December 30 last year, Janet was 13 years old. She turned 14 on her birthday on December 31 last year. On December 31 this year, she will be 15 years old, and on December 31 next year she’ll be 16 years old.
