When do Christmas Party dates start selling out?

[Mom & Popcorn]

We are hoping to attend Mickey's Very Merry Christmas Party for the first time this year. Our trip is first week of December, we're planning on our party night to be during the week. I was hoping to spread out our pre-trip expenses like flights, tickets for this party, and everything else. But I don't want to wait too long that they start selling out for our trip dates. So my question is does anyone know when the Christmas Party tickets start selling out, roughly speaking? If I wait until July or Aug would I be risking it? Thanks for your help everyone.
