Zone 7a (0 to 5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Du Quoin, not a forecast for this year.

About 8 weeks of growing season left in Du Quoin before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/06 isn't a guarantee
04/06 is the middle of 30 years of NOAA records, not a promise. Plant by 03/23 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
