Chaos Zero Nightmare Weekly Schedule arrives on Sunday 15 November 2026 at 18:00 UTC, even though the wider game update went live on 11 November. You’ll find the new board under Activity once it opens, with missions that build up to a maximum of 1,000 weekly progress.
Rewards include Crystals and Operation Disks, which can be exchanged at the Operation Records Shop. Both individual task progress and your overall weekly progress reset every Sunday at 18:00 UTC. That makes the board worth checking early in the week, especially because one of its listed missions requires logging in on four separate days.
Chaos Zero Nightmare Weekly Schedule unlock time and weekly reset
Smilegate has confirmed 15 November at 18:00 UTC as the opening time, not 11 November after maintenance. In November, 18:00 UTC is also 6pm in the UK because the country is on GMT. The same time is used for the Sunday reset each week.
Once the event opens, go to Activity and select Weekly Schedule. You’ll see the objectives and a progress total capped at 1,000. There is no benefit to chasing a total higher than the cap within the same week.
The update notice doesn’t list a separate Captain Level requirement for Weekly Schedule. If the tab isn’t visible, check the opening time first: Sunday 15 November at 18:00 UTC. After that, use the Activity screen for any account-specific access message.
Chaos Zero Nightmare Weekly Schedule tasks and progress
Smilegate lists seven Weekly Schedule objectives in the 11 November notice. They cover everyday activities, Aether use and Chaos clears. Check the in-game board for the full set of objectives and reward milestones when the feature opens.
| Task | Weekly progress |
|---|---|
| Log in one day | 100 |
| Order twice at the Café | 100 |
| Approve ten Ark City Policies | 100 |
| Reach a total of 400 Daily Schedule points | 100 |
| Log in four days | 100 |
| Use 640 Aether | 100 |
| Clear Chaos twice | 120 |
Clearing Chaos twice awards 120 progress, while each of the other six listed tasks awards 100. Those seven total 720, not the 1,000-point weekly cap. The update notice doesn’t itemise every task needed to reach the cap, so follow the available goals in the live board rather than assuming the listed examples are enough.
How to reach 1,000 Weekly Schedule progress
Use the board as a checklist rather than trying to grind one task forever. Log-ins happen naturally across days, while café visits, policies and Daily Schedule points can fit alongside your usual routine. If you plan to spend Aether or run Chaos anyway, those activities can also advance weekly objectives.
Be careful with the task that asks for 400 Daily Schedule points. Completing that particular condition gives 100 weekly progress. It doesn’t give you 400 weekly progress, and the Daily Schedule’s own cap is not the same as the new weekly cap.
Because both the individual objectives and the overall tally reset on Sunday at 18:00 UTC, don’t assume partial work on a long-running goal carries into the next week. The four-day login objective in particular is easier if you start early, rather than discovering it on the final day.
What are Operation Disks used for?
Operation Disks are one of the currencies awarded through the new Weekly Schedule. Smilegate says you can spend them at the Operation Records Shop on various items. The basic process is to earn weekly progress, claim the available reward milestones and exchange the Disks in that shop.
Crystals are also part of the rewards. The notice confirms the currencies but not the exact amount paid at every milestone. Read the reward amounts on the live Weekly Schedule track before deciding which tasks you need to finish.
This means reaching 1,000 is your maximum weekly progress goal, not proof that you’ll receive a specific amount of currency at each hundred-point step. The actual rewards are the listed milestones in the game, and those are what should guide your priorities.
Is Chaos Zero Nightmare Weekly Schedule different from Daily Schedule?
Yes. Daily Schedule is still its own activity system, and the new weekly board can give you a task based on Daily Schedule progress. Think of the weekly board as an extra set of goals that rewards activity across several days, not as a replacement for the daily checklist.
For Chaos Zero Nightmare Weekly Schedule, remember three things: it opens at 18:00 UTC on 15 November, resets at the same time every Sunday and caps at 1,000 progress. Those details will keep you from missing the start or expecting unfinished missions to remain after the reset.
