ZZZ 3.1 Maintenance Schedule & End Time

Zenless Zone Zero’s Version 3.1 maintenance begins on May 7, 2025, at 06:00 (UTC+8) and is scheduled to end at 10:00 (UTC+8) the same day, lasting approximately 4 hours. The exact end time can shift if the development team needs extra time, so players should check the official in-game notice or HoYoverse social media for the final confirmation.

Formula

The end time is simply the start time plus the announced duration. In 24-hour format:

End Time = Start Time + Duration

• Start Time – the exact moment maintenance begins, expressed in hours after midnight (e.g., 06:00 = 6).
• Duration – the official estimate in hours (usually 4 to 5 for a major version update).

All times are given in UTC+8 (Beijing time), which is the server’s reference time zone. If you live elsewhere, convert to your local time before using the formula.

Worked Example

Using the default values from the calculator: start at 06:00 (UTC+8) and duration of 4 hours.

1. Convert 06:00 to minutes: 6 × 60 = 360 minutes after midnight.
2. Add the duration in minutes: 360 + (4 × 60) = 360 + 240 = 600 minutes.
3. Convert back to clock time: 600 ÷ 60 = 10, so 10:00.

The calculator returns 10:00 (UTC+8) as the scheduled end time.

When to Use This Calculator

Use this whenever HoYoverse announces a maintenance window for Zenless Zone Zero, especially for major version updates like 3.1. The official notice gives the start time and an estimated duration, but you might want to convert that to your local time zone or plan when to log back in. The tool is also handy for other HoYoverse games (Genshin Impact, Honkai: Star Rail) that follow the same maintenance pattern.

Remember that the duration is an estimate. If the developers encounter unexpected issues, they extend the window, and the actual end time can be later than the calculation.

How to Read the Result

The result is a 24-hour clock time in UTC+8. For example, 10:00 means 10:00 AM in Beijing time. If you are in a different time zone, convert accordingly:

• UTC+8 is 8 hours ahead of UTC.
• For US Eastern Daylight Time (UTC-4), subtract 12 hours: 10:00 UTC+8 = 22:00 previous day EDT.
• For Central European Summer Time (UTC+2), subtract 6 hours: 10:00 UTC+8 = 04:00 CEST.

If the result shows a time earlier than the start (e.g., 02:00), it means the end time falls on the next calendar day in your local zone.

Common Mistakes and Misconceptions

A frequent error is forgetting that the maintenance time is always in UTC+8, not your local time. Another is assuming the duration is fixed – HoYoverse often states “approximately 4 hours” and can extend it. Also, some players confuse the maintenance start with the version release time; the game goes live right after maintenance ends, but there may be a short delay for server synchronization.

Finally, note that the in-game countdown timer (if any) shows time remaining, not the end time. If you see “3 hours 59 minutes” at 06:05, that does not mean the end time is 10:05 – it means the timer is counting down from the official start.

Why Maintenance Windows Vary

Major version updates (like 3.1) typically take longer than minor patches because they add new characters, story content, and system changes. HoYoverse often uses a 4-hour window for these, but occasionally extends to 5 hours if the update is large. The company also schedules maintenance during off-peak hours for the primary server region (Asia), which is why the start time is early morning UTC+8.

Players in other regions may find the maintenance occurs during their evening or night, which is why checking local time is essential.

Frequently Asked Questions

What time does ZZZ 3.1 maintenance end in my time zone?

Convert 10:00 UTC+8 to your local time. For example, in New York (EDT, UTC-4) it ends at 22:00 the previous day (May 6, 10 PM). In London (BST, UTC+1) it ends at 03:00 on May 7. Use a time zone converter to be precise.

Can I play during maintenance?

No. The servers are offline, and you cannot log in. However, you can still open the game client and see the login screen, but any action that requires a server connection will fail.

What happens if maintenance is extended?

HoYoverse announces extensions on their official Twitter/X and Discord. The compensation for extended maintenance usually includes Polychrome, but the amount is not guaranteed. Always check the official notice after the maintenance ends.

Will I lose my progress if I log in during maintenance?

No. Your account data is stored on the server, and maintenance does not affect it. You simply cannot access the game until the servers are back.

How do I know when maintenance is over?

The game will show a “Server is under maintenance” message until it ends. After that, you can log in normally. The official social media accounts also post a “maintenance complete” announcement.

Why is the maintenance time different from the version update time?

Maintenance is the period when servers are down for the update. The version update becomes available immediately after maintenance ends. There is no separate “update time” – the game is playable as soon as the servers are up.
