Grand Piece Online event
Grand Piece Online Halloween: Schedule, Start Times & Next Countdown
Grand Piece Online is Roblox’s sprawling One Piece-inspired adventure — a pirate-era world of Devil Fruits, sea battles and boss hunts that has pulled in well over a billion visits and still draws tens of thousands of players at once. Each autumn it hands the map over to its biggest seasonal celebration: the Halloween event, a limited-time takeover that layers spooky zones, exclusive gear and cosmetics on top of the usual grind.
Halloween is a yearly fixture rather than a one-off. Developer Grand Quest Games brings it back around late October and rolls it out in parts over the following weeks, so there is fresh content to chase right through the season. The next return and the usual release times are on the card below.

How often Halloween runs, and when
Halloween comes back roughly once a year, each October — a cadence of about every ~359 days between seasons. It has run 2 times so far. The numbered Parts that make up each season tend to drop on a steady weekly rhythm while the event is live, and the developer favours two release windows so players across the world’s timezones can all be online when new content goes live.
Both windows are anchored to Eastern Time — Mondays at 12:00 AM ET and Fridays at 7:30 PM ET. Here is how those slots land across the major regions:
| Window (US East) | US West | UK | Central Europe | India | Japan | Australia (AEDT) |
|---|---|---|---|---|---|---|
| Mon 12:00 AM | Sun 9:00 PM | Mon 5:00 AM | Mon 6:00 AM | Mon 9:30 AM | Mon 1:00 PM | Mon 3:00 PM |
| Fri 7:30 PM | Fri 4:30 PM | Sat 12:30 AM | Sat 1:30 AM | Sat 5:00 AM | Sat 8:30 AM | Sat 10:30 AM |
The clock times stay fixed in ET; the day of the week simply shifts forward for players in Europe, India and the Asia-Pacific region. That is the whole point of running two slots — one falls in a comfortable evening for the Americas, the other catches Europe and Asia-Pacific during their daytime. Because next year’s start hasn’t been locked in yet, the date on the card is our best estimate from the event’s usual timing; we’ll confirm it once the official schedule is posted.
What’s in the Halloween event
The current chapter, Halloween Part 3, reopens Transylvania to the west of Shells Town and builds the season around a few headline activities:
- A new boss, Ba’al, who guards the season’s best loot — including the Moonreaver and its Prestige Eclipse variant, plus the Blood Chains.
- Spooksville Haunts that appear roughly every 25 minutes, handing out Candy and doubled drops with a shot at the Haunted Seeking Pumpkin; clear 25 of them to earn the Monster Hunter title.
- Two fresh Battle Royale maps, one of them Halloween-themed.
- Seasonal cosmetics such as the Witch’s Hat and the All Seeing Nightfall skin, alongside returning outfits and shop weapons.
- Quality-of-life additions that carry over year-round: expanded Custom Tailor support, clearer accessory and outfit previews, an M1 combo indicator, trade requests sent straight from Trading Signs, and private Battle Royale pads that now refill your ultimate bar.
Tips for catching it
- Pick whichever window suits your region — the Friday 7:30 PM ET slot lands in the evening for the Americas, while the Monday midnight ET slot is daytime across Europe and Asia-Pacific.
- Set a reminder a few minutes ahead. Once you’re in, the Spooksville Haunts run on a 25-minute loop, so you can farm Candy steadily without timing anything.
- If you miss the season entirely, it isn’t gone for good — Halloween returns the following October, so there’s always next year.
How Halloween fits Grand Piece Online’s update rhythm
Between seasonal events, Grand Piece Online runs on a mix of large numbered updates, like Update 13, and smaller Mini Updates that tune the game in between. Halloween sits above that cycle as the autumn tentpole, the one time of year the map itself transforms. If you’ve played through a recent Mini Update, the Halloween season is its bigger, time-limited counterpart and worth prioritising while it’s live.
