September is when the holiday party starts to feel real. The venue search is under way or done, the budget has been signed off or is about to be, and somebody asks whether the DJ is booked. This post is about what the December calendar actually looks like from the entertainment side in early September: which dates are already gone, which ones are not, and the order to do things in so you are not chasing a date that no longer exists.
Book the venue first, then the DJ
Sequence matters more than lead time. A DJ cannot hold a date usefully until there is a room, because the room decides most of what goes into the quote: how much sound the space needs, whether the venue requires its house system, where the booth can physically go, what time load-in is permitted, and what the venue wants on a certificate of insurance. Booking entertainment before the venue means holding a date with none of that settled.
Cvent's holiday planning checklist puts entertainment ten to twelve weeks out, alongside venue and catering. For a mid-December party that is late September or early October, which is later than most DJ websites will tell you. The complication is that the venue side of the calendar keeps moving earlier. OpenTable data reported by Restaurant Business shows prime December dates filling from Labor Day onward, with December 10, 16, and 17 among the five biggest group-dining days of the year. So the practical version is: close the venue in September if you can, and send the DJ inquiry the same week you sign, not two months later.
Which December dates go first
Demand is not spread across the month. It stacks on a handful of evenings, and the order is the same every year.
- Fridays and Saturdays in the second and third weeks. In 2026 that is December 11, 12, 18, and 19. These go first with every vendor in the market, and Saturdays go earliest because they also compete with private celebrations. If you want one of these and it is September, ask this week.
- Thursdays in those same weeks. December 10 and 17. These fill next, and a lot of experienced planners prefer them: attendance is higher, the venue is calmer, and the room is not fighting three other parties for cars at the end of the night. There is a longer case for that in the midweek versus Friday post.
- The first week, and any Tuesday or Wednesday. December 1 through 4, and midweek dates throughout the month, stay open well into November. They are not consolation dates. They are often the better party.
- The week of Christmas. December 21 through 23 look open because they are, and they are open because a good part of the office is already traveling. Book them knowing that.
One thing about Saturdays that is invisible from the buyer's side: a Saturday in mid-December is almost never a single event for the venue. There is usually a daytime function turning over into yours, which means the venue offers the DJ a load-in window of ninety minutes before doors instead of the two hours the setup would like, with the caterer resetting tables in the same room at the same time. It is workable and we plan for it, but it is one more reason a Saturday is the tightest date of the year, not only the most contested.
What is actually still open in September
For us, most of December. We are one DJ, which means one event per date, and the calendar fills date by date rather than in blocks. In a typical year, by the first week of September the Saturdays in weeks two and three are the dates most likely to be gone, and the Friday before Christmas week is next. Everything else is usually open, and we will tell you the same day whether a specific date is.
A few things make an inquiry answerable in one reply instead of three:
- The date, or two or three you are deciding between. We check them all at once.
- The venue, even if it is not signed. A hotel ballroom, a restaurant private room, and your own office are three different setups and three different sound requirements.
- A rough headcount and a start and end time. Four hours covers most holiday parties; a 5:30 arrival with a midnight close is extended hours, and it is better to know that at the quote stage than on the night.
- Whether there is a program. A toast, a few remarks, or an awards segment means wireless microphones, and the number of speakers affects how many.
On holding a date: an inquiry holds nothing. A signed agreement and a deposit hold it, with the balance due closer to the event. Between those two points, if a second inquiry comes in for the same date we say so, so nobody is surprised. A date penciled with any vendor is only as good as that vendor's word, and the honest version of that word is that a pencil is not a booking.
Prices do not change for December. The three packages are on the pricing page; the Corporate Celebration package at $3,500 is what most holiday parties are, covering up to four hours from guest arrival through dancing. Lighting is a separate add-on, quoted against the room.
If you are reading this later than September
October is fine for almost any date except a mid-month Saturday. November is where the answer becomes "it depends on the date," and there is a separate post on what is still possible in November. A party in the first week of December, or on a Tuesday, can often be booked three weeks out, and we take short-notice dates when the calendar is open.
What does not compress is the venue's paperwork. Many Manhattan venues, and more New Jersey venues each year, want a certificate of insurance weeks before load-in, with the building owner and operator named as additional insured. When the date is close, the COI goes out the day the agreement is signed, because the venue often will not confirm the load-in without it. The whole decision, including what a DJ does at a company party and what the venue will ask for, is laid out in the holiday party DJ overview.
What to send
The date or dates, the venue, and roughly how many people. From that we can confirm availability, suggest a package, and tell you what the venue is going to need. Use the contact page or call (201) 705-3139. We reply within 24 hours.
