What your zone tells you
A hardiness zone is shorthand for how cold your winter gets. It points to your average last spring frost and first fall frost, and almost every planting date is measured from one of those two days. Warm crops wait until after the last frost. Cool crops go out weeks before it. More on hardiness zones · How frost dates work

Get a notification before each window opens
A printed calendar cannot tap you on the shoulder. Dibble reminds you on the morning each crop is due to be started, sown, transplanted or picked, and you can tick the task off from the notification.
