Why these dates

Spring sowings must go in early - six weeks before last frost - to crop before bolting. The autumn sowing, six to eight weeks before first frost, is usually far more productive.

Overwinters under snow in zone 5 and regrows in spring. One of the few crops that genuinely prefers 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. Spinach are timed for direct sowing 6 weeks before it, and this page simply resolves those offsets against the frost date computed for Hanam.

The median frost-free season here is 199 days, against 40 to 50 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
