Script attivabile solo 3 mesi

Ho questo codice della neve cadente che vorrei attivare solo dicembre-gennaio-febbraio, ho creato il codice (quello rosso) ma non so come applicarlo allo script

<script>
function Neve(){
var calendario = new Date();
var mese = calendario.getMonth();
var nodate = 1;
if (mese == 11 || mese == 0 || mese == 1){
document.write(); var nodate = 0;
}
// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=35

// Set the colors for the snow. Add as many colors as you like
var snowcolor=new Array("#aaaacc","#ddddFF","#ccccDD")

// Set the fonts, that create the snowflakes. Add as many fonts as you like
var snowtype=new Array("Arial Black","Arial Narrow","Times","Comic Sans MS")

// Set the letter that creates your snowflake (recommended:*)
var snowletter="K"

// Set the speed of sinking (recommended values range from 0.3 to 2)
var sinkspeed=0.6

// Set the maximal-size of your snowflaxes
var snowmaxsize=20

// Set the minimal-size of your snowflaxes
var snowminsize=10

// Set the snowing-zone
// Set 1 for all-over-snowing, set 2 for left-side-snowing
// Set 3 for center-snowing, set 4 for right-side-snowing
var snowingzone=1

// Do not edit below this line
var snow=new Array()
var marginbottom
var marginright
var timer
var i_snow=0
var x_mv=new Array();
var crds=new Array();
var lftrght=new Array();
var browserinfos=navigator.userAgent
var ie5=document.all&&document.getElementById&&!browserinfos.match(/Opera/)
var ns6=document.getElementById&&!document.all
var opera=browserinfos.match(/Opera/)
var browserok=ie5||ns6||opera

function randommaker(range) {
rand=Math.floor(range*Math.random())
return rand
}

function initsnow() {
if (ie5 || opera) {
marginbottom = document.body.clientHeight
marginright = document.body.clientWidth
}
else if (ns6) {
marginbottom = window.innerHeight
marginright = window.innerWidth
}
var snowsizerange=snowmaxsize-snowminsize
for (i=0;i<=snowmax;i++) {
crds = 0;
lftrght = Math.random()*15;
x_mv = 0.03 + Math.random()/10;
snow=document.getElementById("s"+i)
snow.style.fontFamily=snowtype[randommaker(snowtype.length)]

snow.style.left=snow.posx
snow.style.top=snow.posy
}
movesnow()
}

function movesnow() {
for (i=0;i<=snowmax;i++) {
crds += x_mv;
snow.posy+=snow.sink
snow.style.left=snow.posx+lftrght*Math.sin(crds);
snow.style.top=snow.posy

if (snow.posy>=marginbottom-2*snow.size || parseInt(snow.style.left)>(marginright-3*lftrght)){

}
if (browserok) {
window.onload=initsnow
}
}
</script>

Semplicemente, metti il codice della neve all'interno della if:

Codice:

function Neve(){
[COLOR="Red"]var calendario = new Date();
var mese = calendario.getMonth();
var nodate = 1; 
if (mese == 11 || mese == 0 || mese == 1){[/COLOR]
[I]//qui metti il codice per l'effetto neve[/I]
[COLOR="red"]}[/COLOR]

Clicca per allargare...

Ok, funziona, ho notato con ie che nella pag in alto a sx, quasi all'angolo appare la K (il carattere al posto del fiocco) eppoi scompare ed appare la K cadente.
Come mai?
