How to Update Your
Wallpaper Every Month
1. OPEN THE APP
Launch Lunar Calendar (or Lunar Ritual 2026) as you normally would—from Applications, the dock, or your desktop.
2. CHECK THE MONTH
The app shows the current month at the top. It updates automatically; no need to change anything when a new month starts.
3. PICK A THEME
LUNAR CALENDAR: lunar calendar artwork for the month
IO CATS: cat-themed artwork for the month
Click the theme you want. The app sets your desktop wallpaper and saves your choice for that month.
4. YOUR DONE!
When the status shows “Wallpaper updated!”, you can close the app. Your wallpaper will stay set until you change it again or run the app next month.
CHANGE THE MONTH:
Run the app once at the start of each month (or whenever you want a fresh wallpaper) and tap your preferred theme.
SWITCH BACK:
Go to your computer’s Wallpaper or Background settings and select a different image. Your original wallpaper is never overwritten and can always be restored.
