If someone was born on February 29, 1992, they would only have a birthday every four years on a leap year. Since the question does not specify the current year, we can assume that the current year is not a leap year. Therefore, if the person was born in 1992, they would have had 16 birthdays (1996, 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, 2048, 2052, 2056) until the present year. However, if the current year is a leap year, the person would have had 17 birthdays.
