The rule for leap years

Divisible by 4 makes a leap year, divisible by 100 takes it back, divisible by 400 grants it again. That is why 1900 was not a leap year and 2000 was.

1948 ÷ 4 = 487, and it is not divisible by 100

Years of 52 weeks and of 53

ISO counts a week as belonging to the year that holds its Thursday. A year runs to 53 weeks only when it contains 53 Thursdays — that is, when 1 January is a Thursday, or a Wednesday in a leap year.

The sixty-year cycle

Ten heavenly stems and twelve earthly branches advance together, one step each year, so the same pair returns only after sixty years. The animal alone repeats every twelve.
