function method(){
var year = document.getElementById("year").value;
var month = document.getElementById("month").value;
var data = new Date(year,month-1,1);
var dataTable = document.getElementById("table");
var cells = dataTable.querySelectorAll("td");
var cells2 = dataTable.querySelectorAll("td+td");

for (var i = 0; i < cells.length; i++){
    var mikro = cells[i].firstChild.data.split("-");
    var place = cells2[i].firstChild.data;
    var firstData = mikro[0].split(".");
    var secondData = mikro[1].split(".");
    var data1 = new Date(firstData[0],firstData[1]-1,1);
    var data2 = new Date(secondData[0],secondData[1]-1,1);
    if(data1<=data && data2>=data){     
        alert(place);
        }
    }
}

Here i have 2 columns in the table, i want to create script which will help me to find information from it: I have <input type="text" id="year" name="year" autofocus/> and <input type="text" name="month" id="month" /> where i can enter year & month.After entering year&month i have to get information from the 2nd column according to the dates on the 1st column for example: " Input year: 2002, Input month:05 - result must be 'Secondary School'" because it between 1999.09-2007.06 . I can't see what is wrong with my script, it always give me false information.

Try this (jsfiddle), increment the cell index by 2 each time, and use the simpler td selector:

function method () {
    var year = document.getElementById("year").value;
    var month = document.getElementById("month").value;
    var data = new Date(year, month - 1, 1);
    var dataTable = document.getElementById("table");
    var cells = dataTable.querySelectorAll("td");

    for (var i = 0; i < cells.length; i+=2) {
        var mikro = cells[i].firstChild.data.split("-");
        var place = cells[i+1].firstChild.data;
        console.log(mikro, place);
        var yearMonth1 = mikro[0].split(".");
        var yearMonth2 = mikro[1].split(".");
        var data1 = new Date(yearMonth1[0], yearMonth1[1] - 1, 1);
        var data2 = new Date(yearMonth2[0], yearMonth2[1] - 1, 1);
        if (data1 <= data && data2 >= data) {
            alert(place);
        }
    }
}
