Mark it now: September 2 through October 31, 2027.
The 2027 Halloween Horror Nights dates are official for Universal Studios Hollywood. The event returns on Thursday, September 2 and runs on select nights through Sunday, October 31. That is a full two-month run ending exactly on Halloween.
The dates came out as part of the park’s 2027 event calendar, which also set Universal Fan Fest Nights for April and laid out the year’s passholder programme.
What you do not have yet is everything else. No house lineup, no scare zones, no ticket prices, and no night-by-night operating calendar. Universal says those land next year.
Here is what the dates tell you, what they do not, and how to plan around a two-month window with no prices attached.
Quick Summary
- Halloween Horror Nights 2027 runs September 2 through October 31 at Universal Studios Hollywood.
- Opening night is Thursday, September 2.
- Closing night is Sunday, October 31, which is Halloween itself.
- The event runs on select nights, not every night.
- The haunted house lineup has not been announced.
- Ticket prices have not been announced.
- Universal says further details arrive next year.
- The dates were released within the park’s 2027 event calendar.
What the Halloween Horror Nights 2027 Dates Actually Confirm
Three useful things, and it is worth separating them from the speculation.
A September 2 start. That is early, and it means the event opens before Labor Day weekend rather than after it. An early-September opening historically gives you the quietest nights of the entire run.
An October 31 close. Ending on Halloween night itself is the ideal close. Some years the event ends in early November, which always feels anticlimactic; this one finishes on the date the whole thing is about.
Roughly two months of operating window. September 2 to October 31 is about 60 calendar days. The event will not run all 60, but a long window means more cheap nights than a compressed one.
Select Nights Is the Catch
This is the detail that costs people money, so read it before you book anything.
Universal has confirmed a start date and an end date. It has not published which nights inside that window the event actually operates.
Halloween Horror Nights has never run nightly for its full season. Early weeks typically operate Thursday through Sunday, expanding as October progresses. Until Universal releases the operating calendar, a date inside the range is not a guarantee of an event night.
Do not buy non-refundable flights for a specific September or October 2027 date yet. You are a long way out, and the night-by-night calendar is the piece you need.
What Has Not Been Announced
Being direct about the gaps, because they are most of the event.
Haunted houses. No lineup, no count, no intellectual property announcements. This is the part fans care about most and it is the part that comes last.
Scare zones. Nothing announced.
Ticket prices. Nothing, including whether pricing structure changes.
Express and R.I.P. tour pricing. Nothing.
Operating nights. Nothing beyond the outer dates.
Universal has said additional details including the house lineup and ticket prices will be announced next year as the event approaches. That is a normal cadence; houses usually trickle out across summer.
A Note on Orlando
Worth flagging because the two coasts get confused constantly.
This announcement is Universal Studios Hollywood in California. Universal Orlando runs its own separate Halloween Horror Nights with a different lineup, different dates and different tickets.
Orlando’s 2027 event has already leaked in a different form: permit filings revealed breakfast-themed house codenames for ten Universal Studios Florida locations. Those codenames apply to Orlando only and tell you nothing about Hollywood’s lineup.
How to Plan This Far Out
You are roughly ten months from opening night. Here is what is actually useful to do now.
Block the window, not the date. Pencil in a September or October 2027 trip without committing to specific nights.
Target early September if budget matters. Opening weeks are consistently the cheapest and least crowded of any HHN season, and a September 2 start gives you several of them.
Avoid the last two October weekends if crowds matter. Those are the busiest nights of the year, every year.
Price a pass before buying event tickets. Hollywood’s annual passes include special ticket offers for HHN, and the new Diamond tier bundles a Halloween Horror Nights ticket outright. If you were already planning to attend, that changes the calculation.
Watch for the operating calendar first, house announcements second. The calendar determines whether your trip works. The houses determine whether you are excited about it.
The Bottom Line
The 2027 Halloween Horror Nights dates put Universal Studios Hollywood’s event from Thursday, September 2 through Sunday, October 31, running on select nights. The dates arrived inside the park’s 2027 event calendar alongside Fan Fest Nights in April.
Everything that makes the event an event, the houses, the scare zones, the prices, is still unannounced and due next year.
Use the window to shape a trip rather than book one. Early September will be the cheapest way in, the final October weekends will be the busiest, and nothing should be locked until Universal publishes which nights actually operate.
