The documentation below describes the old app and is kept for existing users.
Minimal Windows tray app that shows the current ISO week number.
- Displays the current week number in the system tray (no taskbar clutter).
- Auto-start with Windows (optional).
- No installation or background services.
For new installations, use Voltura WeekNumber.
If you still need the old app:
- Download
WeekNumberLite2+.exe - Run the file — that’s it!
When launching for the first time, Windows might show a SmartScreen warning:
- Click More info
- Click Run anyway
This happens because the file is unsigned, but it's safe and open source.
If you find these apps useful, consider supporting development of Voltura WeekNumber:
