One time-axis is the backbone of a second brain — everything dated hangs off it.
One time-axis is the backbone of a second brain — everything dated hangs off it.
Everything dated hangs off a single year to quarter to month to week to day tree. The daily note is an index of the day, not a container; atomic captures land in day-folders; content rolls up along the spine. One predictable axis makes retrieval and AI-enrichment trivial — the assistant always knows where dated things live and where to write them. Cleverness fragments; a spine compounds.
Where it lives: SBM series (The Calendar Is the Spine); calendar-as-spine convention.
