Obsidian Life in Weeks

A dynamic "life in weeks" grid for Obsidian. Visualize your entire life as a grid of weeks — each cell is one week. Lived weeks are colored green, the current week is red, and future weeks are gray. The grid updates automatically every time you open the note.

Inspired by Tim Urban's "Your Life in Weeks".

• Configurable birth date — set birth in frontmatter
• Configurable max age — set maxAge in frontmatter (default: 70)
