Why these dates

Sow from two weeks before the last frost and again from late summer. Warm weather pushes it into flower before the plant has any bulk, so the autumn sowing is the better one.

Hardy to about -6C. Cold weather is what keeps the buds tight, so a frosty autumn produces the best heads.

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. Rapini are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Saltillo.

The median frost-free season here is 297 days, against 40 to 55 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
