I have the following problem, I have a date that comes from the database and compare with the current date, and I do the following:

var dataAtual = new Date();
var partesData = dataAtual.split("/");
var dataAtualNova = new Date(partesData[2], partesData[1] - 1, partesData[0]);
var dataassinado = new Date({vem do banco});

if(dataAtualNova < dataassinado){ //faça algo }

But the current date is for example 17/05/1995 and date coming from the bank comes 17/05/1995 10:45 so if the dates are equal the date that comes from the bank will always be greater than the current date because of the hours, how can I match or take the time?

If the date you have is in this 17/05/1995 10:45 format, you can sort by space and get only the date:

var somenteData = "17/05/1995 10:45".split(" ")[0]; // 17/05/1995 10:45 > 17/05/1995

01.12.2016 / 19:20

Using javascript only

Use the Date.setHours (0, 0, 0, 0) method - passing zero to the constructor to reset the hours
To compare the dates, use the Date.getTime () method that will return an integer with the total milliseconds of the date.

var data1 = new Date(2016, 11, 1, 16, 15, 30); // 01/12/2016 16:15:30
var data2 = new Date(2016, 11, 1); // 01/12/2016 00:00:00

console.log('Comparando com as horas, elas são diferentes:');
console.log(data1.getTime() === data2.getTime());

data1.setHours(0, 0, 0, 0);

console.log('Sem as horas, são iguais.');
console.log(data1.getTime() === data2.getTime());
