What these dates mean in Arizona

Planting usually runs about 84 days, from Nov 10 to Feb 1.

That start date is about 54 days later than the middle of the 42 places in this data set that report winter wheat planting dates (Sep 17).

Harvest usually runs about 48 days, from May 15 to Jul 1.

From the start of the planting window to the start of the harvest window is about 186 days in Arizona, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Arizona. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
