There are five Saturdays in February of leap year, right?

Is wrong. For example, February 1 in 1992 is a Saturday. Because 1992/4=498 is a leap year, there are five Saturdays in February this year. However, since the total number of days in four years is 365×3+366= 146 1 46 1/7 = 208, then February1of the next leap year is definitely not Saturday.

As for Saturdays that will reappear several years later, I tell you: 4×7=28 years later, and in the previous six leap years, February 1 is from Sunday to Friday.
