-- 有局限,不支持跨年查询 比如 12-05 ~ 01-29
select * from user where 
DATE_FORMAT(FROM_UNIXTIME(birthday/1000),'%m-%d') BETWEEN '02-28' AND '09-15';

-- 查询最近七天过生日的人,支持跨年
SELECT *

DATE_ADD(FROM_UNIXTIME(birthday/1000), 
            INTERVAL YEAR(CURDATE())-YEAR(FROM_UNIXTIME(birthday/1000))
                        + IF(DAYOFYEAR(CURDATE()) > DAYOFYEAR(FROM_UNIXTIME(birthday/1000)),1,0) YEAR)  
            BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 30 DAY);

-- 查询 12-04 到 下一年1-4日过生日的
SELECT * 
FROM  user 
WHERE
DATE_ADD(FROM_UNIXTIME(birthday/1000), 
            INTERVAL YEAR(FROM_UNIXTIME(1701662559000/1000))-YEAR(FROM_UNIXTIME(birthday/1000)) + IF(DAYOFYEAR(FROM_UNIXTIME(1701662559000/1000)) > DAYOFYEAR(FROM_UNIXTIME(birthday/1000)),1,0) YEAR)  
BETWEEN FROM_UNIXTIME(1701662559000/1000) AND FROM_UNIXTIME(1704340959000/1000);
