Days to Harvest Calculator

Plan your harvest window. Pick your plant, set your planting date, and we'll compute the rest. Entirely in your browser.

How it works

Pick your crop, choose the variety or method (direct seed vs. transplant, since they have different timelines), and set the day you planted (or plan to plant). The calculator adds the typical days-to-maturity range from published seed-packet and university-extension data, then projects:

First harvest. The earliest day you should start checking.
Peak harvest. The midpoint of the typical window.
Season end. The last day of the typical productive window.

These are averages. Your actual harvest depends on weather, soil quality, sunlight, and variety. The harvest tip below the result tells you exactly what to look for so you don't pick too early or wait too long.
