The data

Quick start

use holiday_engine::{get_china_holidays, is_naturally_off};
use chrono::NaiveDate;

let holidays = get_china_holidays();
let date = NaiveDate::from_ymd_opt(2026, 1, 1).unwrap();
assert!(is_naturally_off(date, &holidays));

// Feb 14, 2026 is a Saturday but an adjusted WORK day
let work_date = NaiveDate::from_ymd_opt(2026, 2, 14).unwrap();
assert!(!is_naturally_off(work_date, &holidays));
