Frost-date / succession planting calendar
Pick a USDA hardiness zone or enter your own last spring / first fall frost dates, choose an outdoor space class, and select 4–8 crops. You get week-range windows for start indoors, transplant, and plant outdoors, plus succession tips for lettuce and radish, and a short cold-frame note. No account. No email. Runs in your browser.
Honest framing: USDA zone maps are coarse. A south wall, frost pocket, elevation, or lake effect can shift dates by 1–3 weeks. Local Extension frost dates and your own microclimate win over any zone dropdown. Numbers here are typical U.S. home-garden offsets — not a guarantee.
Frost anchors & space
Coarse mid-continental midpoints. Prefer local Extension dates when you have them.
Leaves blank → uses zone midpoint. Fill both dates to ignore zone midpoints.
Used for fall/succession cutoffs and cold-frame notes.
None or balcony-only keeps the soft CTA off — stay with Extension and container greens.
Weekend-miracle intent keeps the soft CTA off and flags fantasy timelines.
Crops (pick 4–8)
Soft CTA wants ≥4. Caps at 8 so the calendar stays readable. Offsets are weeks relative to your last / first frost.
