DIABLO IV · LINK GUIDE
Event tracker
Diablo IV tracker for world bosses, Helltide and Legions: countdowns in German time, adjustable alarms, calendar and atlas.
This tracker is for Diablo 4 only.
MODEL & DATA BASIS
How to read the timers
World boss and Legion times are automatically retrieved from Helltides’ public community schedule. Start times are displayed to the minute in Europe/Berlin, including CET/CEST. This is not a confirmed live report from the game server. Missing or outdated source timestamps pause the timer.
| Event | Historical regular interval | Context |
|---|---|---|
| Helltide — schedule model | 60 minutes | Base schedule: start on the UTC hour, 55 active minutes, then a five-minute break. The in-game map confirms the active region. Proposed 3.3 PTR changes, such as offset expansion zones, are not yet a confirmed live schedule. |
| World bosses | 210 minutes | The automatic display uses UTC timestamps supplied by Helltides and converts them to Europe/Berlin. Multiple encounters at one time remain separate. Bosses and regions appear only when supplied. The source is a community schedule, not game-server confirmation. |
| Legion events | 25 minutes | Legion times are also retrieved automatically. The source currently supplies no Legion location: check the in-game map. Events inside a stronghold may require clearing it in your own world first. No automatic start is invented when current source timestamps are missing. |
Reading the time and countdown
Each start lists a date, 24-hour time and time zone. The countdown targets that exact UTC timestamp. Changing the zone changes the display, not the spawn. Germany uses CET (UTC+1) in winter and CEST (UTC+2) in summer; Britain and other European countries may use different zones.
Using reminders and the calendar
Open the alarm settings for your event using the bell icon. Enable its reminder and choose one or two lead times. Sound and system notifications are enabled only when you choose them. Keep the page open and active; closed or operating-system-suspended pages cannot reliably trigger alarms. Use the calendar icon to import the next valid event and reminders as an ICS file. Your calendar then handles its own notifications; later changes to community forecasts are not automatically applied to the imported file.
Daylight-saving changes without duplicated or missing events
Europe/Berlin follows time-zone rules rather than a fixed two-hour addition. On 25 October 2026, 03:00 CEST becomes 02:00 CET. The repeated hour is distinguished by CET/CEST and its UTC offset. Manual references must include an explicit offset.
Before a world boss
Match the date and region, travel to the appropriate arena and check the in-game marker. A second boss listed at the same time is a separate encounter; do not apply the first boss name to both regions. Enemy difficulty and your equipment determine whether the fight is suitable. A timestamp does not guarantee a kill or drop.
Joining a Legion event
Find the map notice, check the waypoint and any stronghold prerequisite, and arrive before the start. The event contains timed enemy waves and Servants of Hell. Focus marked targets and move with the group; scattered leftovers waste time. Location and reward tier cannot be inferred from a 25-minute interval.
When data is missing
Automatic timers pause after a timeout, blocked source or changed data format. Refresh retries retrieval; old data is never presented as freshly checked. An optional manual observation remains a short-lived estimate. Offline, the guide remains readable but cannot provide current server state.
Activities without a global clock
- Whispers and map objectives: Deadlines and targets vary. The in-game marker shows the remaining time; a universal recurring countdown would be misleading.
- Boss lairs and campaign bosses: Players trigger these fights through access and progression. They do not share a world-boss spawn clock. See the destination list in the regional atlas.
- Local events and seasonal encounters: Dependent on instances, objectives, conditions or seasonal mechanics. The current map and quest log take priority; this page does not retrieve server state.
Confirmed dates

Officially announced test window, not a Season 16 launch date. Note the daylight-saving change: October 27 at 10 a.m. PDT to November 3 at 10 a.m. PST. Content and dates can change.
