Icarus Shutdown Timer Calculator

Convert hours and minutes into the exact second values for Icarus's ShutdownIfEmptyFor and ShutdownIfNotJoinedFor settings. Avoid the common traps: 0 shuts down instantly, and the 300-second default kills servers between sessions.

ShutdownIfEmptyFor

Shuts down the server when no players remain. Use for servers you want to stop between sessions.

Calculated value 3600s
✅ Good choice for a persistent server — players returning after a break won't be surprised by a cold server.

ShutdownIfNotJoinedFor

Shuts down the server if no one joins within this many seconds after startup. Prevents orphaned server processes.

Calculated value 3600s

ServerSettings.ini output

ShutdownIfEmptyFor=3600
ShutdownIfNotJoinedFor=3600

For persistent always-on servers, use 86400 (24 hours) or -1 (never) for both settings.

Common Values Reference
