Once per event, at the lead time you picked in Alert before. It does not repeat and it does not ring again while the event is running. The next time that same boss or dungeon comes around, it rings once more. Turning an alarm on affects only that one card, so you can leave five alarms on and stay quiet about everything else.

Browsers refuse to play sound until you have clicked something on the page, so an alarm set on a previous visit stays silent if you only scroll. Press Test once and the sound is unlocked for the rest of the session. Also check that the speaker button is on, that the volume slider is not at zero, and keep the tab open. The page cannot alert you after it is closed.

Live means Wemade published how long the window stays open, so the card counts down to the moment it closes and a bar underneath shows how much is left. Spawned means the boss has just appeared but the game never published a despawn time. That card counts up instead, showing how long ago it arrived, and it drops back into the queue after thirty minutes.

Both clocks sit at the top of the page. Times in switches every countdown and every day heading between them, so if you play on ASIA from Brazil you can read the whole schedule on your own clock and stop doing the maths. The Today and Tomorrow groups follow whichever clock you picked, which is why an event can move between them when you switch.

No. Every boss, dungeon and clan event fires at the same local server time in ASIA, INMENA, EU, NA and SA. The daily reset is the one exception: it happens at a single moment worldwide, 16:00 UTC, which is why it reads as 18:00 on EU, 12:00 on NA and midnight on ASIA. Those are the same instant, not different schedules.

One per night from Monday to Friday: Krukan on Monday, Nerkan on Tuesday, Helbar on Wednesday, Turkan on Thursday and Utukan on Friday. Nerkan and Turkan appear sealed at 19:00 and only become killable at 23:00, so the card counts down to 23:00, the time that is actually worth showing up for. Krukan and Utukan cap the area at 450 players and there is no fast travel, so leave early.

Your region, filters, alarms, clock choice, alert time and volume are stored in this browser. No account needed, but they do not travel to your phone or another computer. The region also lives in the address bar, so a link like /timing?region=eu opens on that region for whoever you send it to. Handy when you are pasting times into a clan chat.

The countdown reads your system clock every second rather than counting ticks down, so it is still correct after your computer wakes from sleep. A hidden tab is a different matter: browsers throttle background timers, so an alarm can arrive up to a minute late. If a spawn really matters, keep the tab visible or give yourself a longer lead time.

Most of the schedule comes from Wemade's own notices and encyclopedia. Two things do not. The Fury and Frenzy Chamber hours have never been published, so those come from community observation. And the thirty minute window on a Spawned boss is our display choice, not an in-game timer, because the game does not say how long those bosses stay. Redmoon Purgatory is the exception there, its five minutes is official.
