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.
Two-way sync with your real calendar. Add on your desktop, see it on your phone seconds later, and vice versa. Deletes, edits and skips flow both ways.
Press Ctrl+Shift+Space in any app and type “standup every monday 9:30am”. Done. You never left what you were doing.
Month on one screen, your notes board on another, this week’s agenda on a third. Each wallpaper shows what you choose, all in sync.
“Move my dentist to next week.” “When is mom’s birthday?” Plug in an Anthropic API key and just tell your wallpaper what you want.
Eleven background themes across dark and light modes, and Auto mode follows your city’s real sunrise and sunset.
Timer with chimes, local weather with optional rain & snow effects on the wallpaper itself, a morning briefing, and Spotify controls under the clock.
A sticky-note board and to-do list one tab away. US holidays built in. Pin any event as a big countdown under the clock.
Works without an account and saves to plain files on your machine. Sync is optional. Even the Pro license verifies offline. Your data is yours.
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.
Free is the full calendar, forever. Pro is for power users: one payment, one key, yours for good.
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. Free tier and Pro are identical to Windows, and one Pro key unlocks both.
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.
It appears on the page you land on right after payment. Copy it, then on your desktop open ⚙ Settings → License → paste → Activate. Lost it? The link in your Stripe email receipt reopens the page with your key any time.
No accounts, no telemetry. Events live in plain JSON files under your own user folder. Google sync only runs if you connect it. Even Pro keys are verified offline with cryptography. The app never calls a license server.
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.
