CmdScheduler+ | In-Game Calendar, Commands, Restarts & Announcements [1.21.x]

Server automation should feel obvious.

CmdScheduler replaces cryptic cron expressions and schedule files with a polished calendar your staff can operate entirely in game.

Create a weekly reward in seconds:

Every screen guides the user forward, explains each choice, and provides clear navigation back. Normal administration, including timezone, restart command, reminder defaults, history retention, and interface sounds, is available from the GUI.
A real calendar; not a command wrapper

• Weekly calendar with scheduled events visible on each day
• Full month view with month and year navigation for long-range planning
• Day, upcoming, search, category filter, and execution-history views
• Visual date and time pickers with custom input when needed
• Every event shows what it is, when it runs, its next occurrence, and whether it is enabled

Schedule practically anything

Console commands
Run any command as console; perfect for rewards, maintenance, minigames, broadcasts, and existing plugin integrations.

Styled announcements
Send announcements through chat, title, action bar, bossbar, or chat and title together. Supports classic &a/ &l, hex colors, and MiniMessage with a live preview.

Restart countdowns
Create clean scheduled restart flows using your server's configured restart command and configurable warnings.

Reminders
Notify everyone or staff before an event. Configure multiple reminder times and an optional live bossbar countdown.

Multiple actions
Build an ordered sequence of commands, announcements, reminders, restarts, and delays. Choose whether the sequence stops or continues when an action fails.


Powerful recurrence without cron syntax

• One time
• Daily
• Weekly or selected weekdays
• Monthly
• Weekdays or weekends
• Every X days or weeks
• Optional ending date or maximum run count

CmdScheduler prevents a one-time event from being saved after its execution time has passed. Older one-time events are clearly marked as expired instead of silently doing nothing.

Designed for schedules you need to trust

• Timezone-aware scheduling that preserves the selected local time across daylight-saving changes
• Durable SQLite storage with WAL safety
• Duplicate-run prevention using unique occurrence records and in-flight guards
• Missed-run policies: skip the occurrence or run it when the server starts
• Execution history with success, partial, failed, and skipped statuses
• Visible failure alerts for administrators
• Schedule-overlap and restart-conflict warnings
• Lightweight runtime with cached schedules and no per-tick database scan

Make it match your server

Every player-facing message and every GUI is configurable.

• Prefix, prompts, validation, reminders, warnings, and command feedback
• GUI titles, slots, materials, item names, lore, borders, fillers, and click hints
• MiniMessage, legacy ampersand colors, and hex colors
• Reload changes with /schedule reload—no server restart required

Commands
Aliases: /calendar, /scheduler

Metrics
CmdScheduler+ uses bStats to collect anonymous usage statistics (server version, Java version, player count, etc.). These metrics help guide development and are opt-in by default through plugins/bStats/config.yml on your server. These metrics greatly help me and have no affect on server performance, so if you could leave this on please do.
