Expand description
Primitive calendar year helpers.
These helpers keep leap-year and year-boundary calculations explicit.
§Examples
use use_year::{CalendarYear, first_day_of_year, last_day_of_year};
let year = CalendarYear::new(2024);
assert!(year.is_leap_year());
assert_eq!(year.days_in_year(), 366);
assert_eq!(first_day_of_year(2024).unwrap().month(), 1);
assert_eq!(last_day_of_year(2024).unwrap().day(), 31);
