Why these dates

Sow as soon as soil is workable - six weeks before last frost is normal. In mild-winter climates an autumn sowing overwinters and crops six weeks earlier than any spring sowing can.

Established pea plants shrug off -6C. Seedlings tolerate frost easily; it is heat, not cold, that ends the crop.

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. Peas are timed for direct sowing 6 weeks before it, and this page simply resolves those offsets against the frost date computed for Phnom Penh.
