Why these dates
Killed by any frost. Needs roughly 90 warm frost-free days to dry a crop down.
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. Mung beans are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Formosa.
The median frost-free season here is 338 days, against 75 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
