Zone 7b (5 to 10°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 Friendsville, not a forecast for this year.

Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
