Not a widget. Not another window. Wallpaper Calendar lives inside your actual Windows wallpaper, behind your icons, under everything, always there.
Windows 11 · macOS 12+ · free forever · no account · your data never leaves your PC · portable .zip
Not a video: the real thing, running in your browser. Click a day and add an event. Drag it somewhere else. Try typing “lunch fri 1pm” in Quick add. On your desktop it lives behind your icons.
Click any day on your background to add events. Drag chips between days, undo mistakes, skip one day of a repeating series. Ctrl+Shift+right-click anything for a quick menu.
Press Ctrl+Shift+Space in any app and type “standup every monday 9:30am”. Done. You never left what you were doing.
Six dark and five light background themes, and Auto mode follows your city’s real sunrise and sunset.
Timer with chimes, local weather under the clock, a morning briefing, and Spotify controls right on the wallpaper.
A sticky-note board, a to-do list and longer notepads one tab away. Join a shared calendar with an invite code and its events, notes and to-dos sync to everyone on it. US holidays built in.
Works without an account and saves to plain files on your machine. Sync is optional. Your data is yours.
Settings has a Styles page: the clock, the editor, the corners, the shared panel and every theme shown as live pictures of your own calendar, so you see each look before you pick it.
Coming soon.
Windows has a hidden layer between your wallpaper image and your desktop icons. Wallpaper Calendar parks a live, interactive surface exactly there: the same trick Wallpaper Engine uses, but purpose-built for getting your life organized. One small tray app, no browser windows, no Electron, nothing else running. Your files and apps always win clicks. The calendar stays politely underneath.
That’s Microsoft SmartScreen being cautious about new independent apps. It appears for any program that hasn’t accumulated a download history yet, not because anything is wrong. Click More info → Run anyway. The app is a single small executable; everything it does stays on your machine.
Windows 11 (the WebView2 runtime it uses ships with Windows). Run the installer: no admin rights needed, it installs just for your user, adds a Start Menu entry, and starts with Windows. Prefer no installer? There’s a portable zip too.
Yes. The Mac version just landed (beta, macOS 12+). Download the Mac zip, unzip it, and right-click WallpaperCalendar → Open the first time (it isn’t Apple-signed yet, so macOS asks once; on newer versions use System Settings → Privacy & Security → “Open Anyway”). Then click the 📅 menu-bar icon → Hide Desktop Icons so the calendar can take your clicks. It is the same calendar as on Windows.
The installed app quietly checks this site a few times a day. When a new version is out it downloads in the background and a small tray notification appears. Right-click the tray icon → Install update, and about five seconds later you’re on the new version. Nothing installs without your click, and your events are never touched.
No accounts, no telemetry. Events live in plain JSON files under your own user folder. Two things reach the internet, and only these: the weather forecast for the city you set and calendar feeds if you turn them on, plus the update check. There is also a Detect button on the weather setting that works out your city from your IP address, which is the one feature that tells an outside service roughly where you are. It runs only when you press it.
Yes. That’s the point. Icons, files and apps sit on top and always win clicks. The calendar only reacts when you click actual empty wallpaper, and a plain right-click still opens the normal Windows menu.
A feature you wish it had, something that broke, or just how you use it. Every message goes straight to the developer.
