Animal Hospital (Anomaly) Halloween: Start Time & Countdown

Halloween is the seasonal event that brings a spooky overhaul to Animal Hospital (Anomaly), the horror-tinged Roblox hospital sim that has pulled in over 2.4 billion visits and keeps more than about 23,000 players in its wards at a time. Rather than a one-off drop, it returns on a regular rhythm, so there is always a next window to aim for.

The event comes back roughly every ten days, landing in two fixed time-of-day slots so players around the world can reach it. The most recent outing was Halloween – Part 2, and the next run opens on Tuesday, October 27 at 3 PM ET. The next start time, the countdown, and the usual windows are on the card below.

How often Halloween runs

Halloween follows a every ~10 days cadence and has already come around 2 times. Each cycle opens in one of two recurring slots: a Tuesday afternoon window and a Saturday afternoon window, both set in Eastern Time. Two windows exist for a simple reason — a single fixed hour would land in the middle of the night for half the planet, so the developer spreads the event across slots that suit different regions.

Here is how the two windows fall across the major regions:

Clocks shift slightly around daylight-saving changeovers, but the ET anchor stays the same.

What happens in Halloween

Halloween leans into the game’s eerie side, dressing the hospital in seasonal decor and layering in limited-time content on top of the usual shifts. Expect the kind of themed additions that fit a horror-flavoured sim:

• A spooky reskin of the hospital and its grounds for the duration of the window
• Event-only activities and rewards tied to the season that are not around the rest of the year
• Fresh content that extends the game’s ongoing lore, continuing threads from earlier updates

Because the run is time-boxed, anything exclusive to it is worth grabbing while the window is live.

Tips for catching it

• Pick the window that suits you — the Saturday afternoon slot is the friendlier one for most European and US players, while the Tuesday slot works well for Pacific daytimes.
• Set a reminder a few minutes ahead so you are in-game when the window opens rather than loading in late.
• Miss it? There is no need to rush — the event returns on its next cycle, so the following window is only about a week and a half away.

How it fits the game’s rhythm

Animal Hospital (Anomaly) runs a steady stream of events, from coin-boost weekends to story beats like Even More Lore, Second Floor, and Ron. Halloween sits alongside these as the seasonal entry in that rotation — a recurring fixture rather than a passing promo, giving regulars a reliable reason to check back every cycle.
