mysql中between and或大于小于查时间，单双引号问题

mysql查询时间时，between and和大于小于都可以
单引号，双引号都可以加在时间上，结果一样

以下sql文查询结果都一样

SELECT * FROM tb_user where birthday between '2021-01-01' and '2021-05-05';
SELECT * FROM tb_user where birthday between "2021-01-01" and "2021-05-05";
SELECT * FROM tb_user where birthday between '2021-01-01' and "2021-05-05";
select * from tb_user where birthday >= '2021-01-01' and birthday <='2021-05-05';
select * from tb_user where birthday >= 2021-01-01 and birthday <= '2021-05-05';
select * from tb_user where birthday >= "2021-01-01" and birthday <= "2021-05-05";
select * from tb_user where birthday >= "2021-01-01" and birthday <= '2021-05-05';
