A clear answer. Here’s how.

Adds your signed whole-day offsets to a supplied frost reference date. Negative offsets are before the reference, positive after; an empty transplant offset remains blank. Accepts up to 1,000 crop rows and offsets from −3650 to 3650 days. No frost history, regional calendar or suitable crop dates are inferred; choose them for your location and seed instructions.
