Zombies Event Schedule: Build & Kill Guide

This page explains how to find and use the build and kill zombies event schedule in popular zombie games, covering what the events are, how they work, and how to plan your play. You’ll learn where to check official schedules, how event timers work, and common mistakes to avoid.

Formula

The calculator estimates the start and end of a zombie event based on the number of days until it begins and the event’s duration in minutes. The formula is:

Event start (days) = Days until event

Event end (days) = Days until event + (Event duration in minutes / 1440)

Where:

• Days until event – the number of full days from today until the event starts (enter a positive number).
• Event duration (min) – how long the event lasts, in minutes (e.g., 60 for a 1-hour event).
• 1440 – the number of minutes in a day (24 hours × 60 minutes).

The result shows the event’s start and end as days from now, which you can convert to a calendar date.

Worked Example

Using the default values: days until event = 3, event duration = 60 minutes.

• Event start = 3 days from now.
• Event end = 3 + (60 / 1440) = 3 + 0.0417 = 3.0417 days from now.

So the event starts in 3 days and ends about 1 hour later (0.0417 days).

What Are Build and Kill Zombies Events?

Many zombie survival games, especially those in the survival-crafting genre (like 7 Days to Die, Project Zomboid, or mobile games like Last Day on Earth), run periodic in-game events where players must build defenses and kill waves of zombies. These events often have a fixed schedule—daily, weekly, or tied to real-world holidays. The schedule tells you when a horde will attack, how long it lasts, and what rewards you can earn.

For example, in 7 Days to Die, a blood moon horde occurs every 7 days by default, but the exact day and time can be set in the world options. In mobile games, events might run for a weekend or a week, with specific start and end times announced in the game’s news tab.

How to Find the Official Schedule

Official schedules are usually posted in three places:

• In-game news or event calendar – most games have a menu that lists current and upcoming events with dates and times.
• Official game website or forums – developers often post a monthly or seasonal event calendar.
• Social media accounts (Twitter/X, Discord, Reddit) – quick announcements for surprise or limited-time events.

If you can’t find a schedule, check the game’s wiki—community editors usually keep an up-to-date event list. For games with server-based events, the schedule may be set by the server admin, so check the server’s rules or Discord.

How Event Timers Work

Event timers are usually based on your local time or the server’s time zone. For example, a daily event might reset at midnight UTC, or a weekly horde might start at 22:00 every Friday. The game will display the time in your local time zone if it’s set correctly. If you’re playing on a multiplayer server, the server’s time zone is what matters—not your own.

Some events have a countdown timer on the main menu or in the HUD. Others are triggered by in-game conditions, like reaching a certain day or completing a quest. Always read the event description to know whether it’s a timed event or a conditional one.

How to Prepare for a Build and Kill Event

Preparation is key to surviving a zombie event. Here’s a checklist:

• Gather materials – wood, stone, metal, and ammunition. You’ll need more than you think.
• Reinforce your base – repair walls, doors, and traps. Add extra layers if the event is a horde.
• Stock up on healing items – bandages, medkits, food, and water.
• Set up defenses – place spike traps, barbed wire, or turrets in choke points.
• Upgrade weapons – repair and reload your best guns or melee weapons.
• Plan an escape route – if your base falls, you need a way out.

For a build event (where you must construct something), make sure you have the required blueprints and resources before the timer starts.

Common Mistakes and Misconceptions

One common mistake is assuming the event schedule is the same for all game modes. In 7 Days to Die, for example, the blood moon frequency can be changed in the world settings, so a server might have hordes every 3 days instead of 7. Always check the specific server settings.

Another misconception is that events always start at the same time every day. Some events have a random start time within a window, or they rotate between different time slots. If you miss the start, you might have to wait for the next cycle.

Finally, don’t ignore the event’s end time. Some events have a “grace period� where zombies stop spawning but you can still collect rewards. If you leave the game before the event ends, you might lose unclaimed loot.

Comparing Different Games’ Schedules

Different games handle schedules differently:

• 7 Days to Die – blood moon horde every 7 days (default), starting at 22:00 game time, ending at 04:00. The day count resets on death? No, it’s based on the world’s day counter.
• Project Zomboid – no fixed events; the helicopter event and horde migration are random, not scheduled.
• Last Day on Earth – events like “The Blind Oneâ€� or “The Witchâ€� appear on a timer, often every 2-3 days, with a countdown visible on the map.
• Dying Light – the “Volatile Hordeâ€� event is a community event that runs for a limited time, announced on social media.

Always check the specific game’s official sources, as schedules change with patches.

Costs and Rewards

Most build and kill events are free to participate, but they may require in-game resources or premium currency to get the best rewards. For example, you might need to buy a special weapon or a base blueprint. Rewards typically include experience points, rare items, skins, or in-game currency. Some events have a leaderboard where top players get exclusive prizes.

Be cautious about spending real money on events—always read the terms and understand what you’re getting. Some events are “pay-to-win� but many are balanced so free players can still complete them.

Safety and Fair Play

When playing online, never share your account credentials to “boost� your event progress. That can lead to account bans. Also, be aware of phishing scams that promise event rewards in exchange for personal information. Stick to official channels for event news.

In terms of gameplay, always follow the game’s rules. Using exploits or cheats to complete events faster can result in a permanent ban. If you’re unsure about a rule, contact the game’s support.

Frequently Asked Questions

How often do build and kill zombie events happen?
It depends on the game. Some have daily events, others weekly or monthly. Check the in-game calendar or official social media for the current schedule.

Can I change the event schedule in my single-player game?
Yes, in many games you can adjust event frequency in the settings. For example, in 7 Days to Die, you can set the blood moon frequency to every 1-30 days.

What happens if I miss the event start time?
You’ll have to wait for the next occurrence. Some events repeat on a cycle, so you won’t miss out permanently, but you might lose a one-time reward.

Do events require an internet connection?
For online games, yes. For single-player, events are usually part of the game’s code and don’t need a connection, but they may be tied to your system clock.

How do I know if an event is active?
Look for a timer icon on the main menu, a banner in the news section, or an in-game notification. Some games also show a countdown on the map.

Can I participate in events on a private server with custom rules?
Yes, but the schedule may be different. Private server admins can often set event times manually. Check the server’s rules or ask the admin.
