A minimalist shutdown, sleep and hibernate scheduler for Windows, built as a Windhawk mod. Work in progress.
Crazy Time schedules shutdown, sleep or hibernate on Windows. Each schedule can be by duration (1 minute to 7 days), at a date and time, or repeating on chosen weekdays. You can keep several schedules at once, edit, pause, cancel a single occurrence, postpone it by 10 minutes, or delete it. The list is restored when the app reopens.
- Countdown warnings at 30, 15, 10, 5 and 1 minute, with optional sound.
- Schedules at the same instant are detected and refused.
- Optional "force apps to close" per schedule (shutdown only), off by default, with a data-loss warning.
- Actions this computer cannot perform are explained instead of being scheduled.
- Portuguese and English UI; automatic, light or dark theme; high contrast.
The mod really shuts down, sleeps or hibernates your computer when a schedule fires (
WindowsPowerBackend). Save your work first, and try a short sleep before relying on it. The real path was manually tested on Windows 11 by the author (report of 2026-10-12, no detailed per-action record). Only the local preview (scripts/build-preview.ps1) runs in simulation, using aSimulatedBackend, and never touches the computer.
Tested on Windows 11 with Windhawk 1.7.x. Windows 10 has not been verified. It is expected to work, but please report problems. It has not been submitted to the Windhawk catalog yet; see the release checklist. Technical documentation in docs/ is in Portuguese.
Easy install: once a release exists, download crazy-time.wh.cpp from the Releases page and paste it into the Windhawk editor (steps are in the release notes).
To build it yourself, you need Windhawk with its compiler installed (C:\Program Files\Windhawk) and PowerShell.
./scripts/test.ps1 # scheduler, schedule book, storage, calendar, warnings
./scripts/test-executor.ps1 # power executor with a fake backend
./scripts/build-preview.ps1 # optional: simulated UI preview in build/preview/
./scripts/build-mod.ps1 # generates build/mod/crazy-time.wh.cpp- In Windhawk, create a new mod and replace the whole template with the contents of
build/mod/crazy-time.wh.cpp. - Compile it (Ctrl+B) and enable the mod. A tray icon appears.
- Click the icon to open the panel, pick an action and how it is scheduled, then press Schedule action.
Details: local installation (Portuguese).
A portable core (src/: scheduler, calendar rules, schedule book, storage codec, warning tracker, power executor interface) is separated from the Win32 host (src/windows/: tray icon, UI, file storage, local calendar, real power backend). The portable tests run anywhere; CI (.github/workflows/ci.yml) runs them on Linux. Storage, calendar and the mod build need Windows and the Windhawk compiler.
Normal shutdown never forces applications; forcing is an explicit, per-schedule opt-in. Sleep and hibernate never force and keep wake events. A failed or rejected request is never retried automatically and does not cancel the next weekly repetition. See ADR 009 for the Windows limits (Portuguese).
