I have the following code to get a range of dates and send to my PHP function (which is ok already):
function calcular(){
var quantidade = document.getElementById('qnt').value;
var inicio = document.getElementById('inicio').value;
var fim = document.getElementById('fim').value;
var total = (((Date.parse(fim)) - (Date.parse(inicio))) / (24 * 60 * 60 * 1000));
total++;//para incluir o primeiro dia
document.getElementById('dias').innerHTML=(total)+" dias<br>";
qtd = quantidade/total;
document.getElementById('entrevistas').innerHTML=(qtd)+" entrevistas p/ dia<br>";
inicio = new Date(Date.parse(inicio));
for(i=1;i<=total;i++) {
var dia = new Date();
dia.setDate(inicio.getDate()+i);
document.getElementById('resultado').innerHTML += "<input type='checkbox' checked onclick='redivide()' name='dias' value='"+dia+"'>"+(dia.getDate())+"/"+(dia.getMonth()+1)+"/"+dia.getFullYear()+"<br>";
}
document.getElementById('resultado').innerHTML += "<input type='button' onclick='envia()' value='Salvar'><div id='resultado2'></div>";
}
function redivide(){
var checks = document.getElementsByName('dias');
var total=0;
for(i=0;i<checks.length;i++){
if(checks[i].checked){
total++;
}
}
var quantidade = document.getElementById('qnt').value;
document.getElementById('entrevistas').innerHTML=(quantidade/total)+" entrevistas p/ dia<br>";
}
function envia(){
var checks = document.getElementsByName('dias');
var vetor_datas = []; var j=0;
for(i=0;i<checks.length;i++){
if(checks[i].checked){
vetor_datas[j] = checks[i].value;
j++;
}
}
document.getElementById('resultado2').innerHTML = vetor_datas;
} <!DOCTYPE html>

When I try to generate for a range that starts on the first day of the month, it gives error in the script. I tried to pack here but I could not. The interesting thing is that it works for the other dates (the beginning of the interval is not the first day of the month).
