Why these dates
Killed by frost, having usually already scattered enough seed to return.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Epazote are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Chengzhong.
The median frost-free season here is 270 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
