SAGE Crop Calendar / GGCMI Phase 3 (UW–Madison SAGE / GGCMI)
Planting and harvest dates for ~19 crops globally.
What this is
The UW–Madison SAGE crop calendar and its successor GGCMI Phase 3 provide gridded planting and harvest dates for major crops globally at 5-arcmin and 0.5°. Available as bulk downloads from SAGE and on Zenodo.
Why we surface it
A crop map tells you what's growing. A crop calendar tells you when it's in the ground. Combined with weather layers, it supports growing-degree-day tracking, spray-window estimation, and seasonal stress timing.
What you can do with it
Shown for commercial use. Personal, research, and nonprofit use is often more permissive — switch the verdict lens on the catalog.

This decoder is a starting point, not legal advice. For commercial deployment, run the actual license terms past someone who reads them for a living.
Good to know
Two license regimes here: GGCMI Phase 3 (Zenodo 5062513) is confirmed CC-BY-4.0 — attribute and use freely. The older SAGE base calendar (Sacks et al. 2010) states academic/non-commercial use on its download page; redistribution or commercial use needs permission from UW-Madison SAGE directly.
