Response in English: No, the year 2021 is not a leap year. A leap year is one that is divisible by 4, except for end-of-century years, that must be divisible by 400. This means that the year 2000 was a leap year, but the years 1700, 1800, and 1900 were not. The year 2021 is not divisible by 4, so it is not a leap year. .
