Overview

The 13-Day Sprint Method combines ancient Maya wisdom with modern agile project management. Instead of traditional 2-week sprints, this system uses 13-day cycles aligned with natural tones of creation. Each day has a specific focus that guides your actions and maintains momentum without burnout.

Why 13 days instead of 14?

The fact that you don't have a strict day of the week for an exact task prevents you from feeling like Groundhog Day with a repeating story. This is important when you're running sprints over a long distance.
