Where does the name "43 Folders" come from?

This site’s name refers to the number of manila folders required to build a physical tickler file system.

Twelve monthly folders and 31 daily folders are used to build a rotating, one-year “look ahead” system. Maintained daily, it’s a powerful lofi hack for never forgetting to do something (and, consequently, not having to worry about forgetting to do something).

It beats (or at least complements) your electronic calendar in at least one way by letting you store hard-copy items like cards or bills in the folder associated with any day between now and a year from now.
