Calendar Forge

Merge, clean, and rename .ics calendar files into a single import-ready file. Strip attendees, reminders, and vendor clutter so old events don't trigger notifications. Filter by date, add per-file prefixes or postfixes, and deduplicate across sources.

• Python 3.8+
• tkinter — included with most Python installs. Ubuntu: sudo apt install python3-tk

All other dependencies are bundled in 01_App/lib/ — no pip, no internet required.

Windows — copy the folder to a local path first (e.g. C:\CalendarForge\), then:

run_calendarforge.bat

Linux / Mac

bash run_calendarforge.sh

1. Drop .ics files into 03_Input/ — they auto-load on launch
2. Set per-file prefix / postfix on the Files tab if needed
3. Configure strip options on the Options tab
4. Hit Generate on the Output tab
5. Import 04_Output/merged.ics into Google Calendar, Outlook, or Apple Calendar
