ZettelID Naming System

Create unlimited events with identical display names while maintaining unique file storage behind the scenes.

How It Works

Prisma Calendar uses timestamp-based unique identifiers (ZettelIDs) that are automatically appended to filenames but stripped from the calendar display.

Display: Team Meeting (everywhere in the calendar UI)

Storage: Team Meeting-20250106143022.md (file system and vault browser)

ZettelID Format

Format: -YYYYMMDDHHmmss (14-digit timestamp)

Example: -20250106143022 = January 6, 2025 at 14:30:22

This ensures every filename is unique, even when creating multiple events rapidly.

Configuration

Optional: Configure a ZettelID property in Settings → Properties to store the ZettelID in frontmatter.

Note: ZettelID filenames work automatically whether or not you configure the property. The property just adds the ZettelID to frontmatter for additional tracking.

Benefits

• Create unlimited events with identical names
• Clean UI without timestamp clutter
• Automatic collision prevention
• Works with all calendar features (recurring events, batch operations, undo/redo)

Manual Events

Prisma format (-YYYYMMDDHHmmss): ZettelID is recognized and stripped from display. When cloning, the existing ZettelID is preserved.

Other formats (e.g., Meeting-2025-01-06.md): Full filename displayed. Cloning adds a new ZettelID, resulting in double timestamps.

Recommendation: Create events via the calendar interface for best results.
