Days in a year

You are given a year $y$. Find how many days it has: a leap year has $366$ days, an ordinary year has $365$.

The leap year rule: a year divisible by $4$ is a leap year, but among years divisible by $100$ only those also divisible by $400$ are leap years. For example, $1900$ and $2100$ are not leap years, $2000$ and $2020$ are.

A single integer $y$ ($1 \le y \le 10^9$).

A single number: $365$ or $366$.

The rule fits in one expression: ($y$ divisible by $4$ and not by $100$) or $y$ divisible by $400$.
