Answer 1

you can do something like this with javascript

window.onload = () => {

const dates = new Array(31).fill(0).map((v, id) => {
const option = document.createElement('option');
option.value = id;
option.textContent = id;
return option;
});
document.querySelector(".dates")
.append(...dates);
};

or you can use
<input type=date name="birthdate"/>
