Why these dates

Sow two weeks after the last frost. Pick constantly from midsummer; the plant crops until the first frost provided nothing is left to mature on it.

Killed at 0C, with no partial hardiness at all. The whole plant collapses the morning after the first frost.

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. Patty pan squash are timed from 3 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Pingliang.

The median frost-free season here is 195 days, against 50 to 65 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
