Which of these years is a leap year: 1800, 1911, 2128, 1951?

💡 Solution & Explanation

A year is a leap year if it divides exactly by 4, except century years, which must divide exactly by 400. 2128 divides by 4 and is not a century year, so it is a leap year. 1800 is a century year that does not divide by 400, so it is not a leap year, and the others do not divide by 4.
