Work backward from your frost date to start seeds

Seed-starting planner
Count back from a planting target to a practical sowing window.
Crop planning example
Use your seed packet and local extension guidance. A frost date is a probability, not a promise; warm-season crops also need suitable soil and nighttime temperatures.
Start with your local date.
Enter the frost date you choose for your garden. No location access or account needed.
Timing and sources
The transplant target is your frost date plus your chosen offset. Indoor sowing is counted backward from that target. Hardening off typically begins one to two weeks before transplanting, with protection from inappropriate cold, wind and intense sun.
