Why these dates

Sow from three weeks before last frost, then every three weeks until ten weeks before first frost. Small roots taste better than large ones.

Seedlings take a light frost. Very early sowings into cold soil can trigger bolting later, so do not rush the first one.

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. Beetroot are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Chiba.

The median frost-free season here is 291 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
