Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.
Sow for autumn
28 Jun - 19 Jul
Counting back 84 days from your first frost so the crop matures in time.
Sow direct
17 Apr - 8 May
Held back until the soil is warm enough for this crop. The frost date on its own would say 20 Mar, which is too cold for it to start.
Harvest
11-26 Jun
Peas through the year
Against the frost risk in Rybinsk
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 Rybinsk.
With one correction, which is the note at the top of the page: the offset alone would put this crop in soil that is still too cold for it. Where the frost date and the soil temperature disagree, the dates here follow the soil, because a seed in cold ground either rots or waits, and a sowing made a fortnight later usually overtakes it.
The median frost-free season here is 164 days, against 55 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing peas in Rybinsk
When should I plant peas in Rybinsk?
Aim for 17 Apr - 8 May in an average year. If you would rather not gamble on the weather, wait until 16 Apr - 7 May - by then frost has finished in nine years out of ten.
Can I plant peas earlier in Rybinsk?
Frost is finished by about 20 Mar, but the soil is still too cold. Peas will not start until it reaches 4.5°C (40.1°F), and here that is around 17 Apr. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
When will peas be ready to harvest in Rybinsk?
Expect to start picking around 11-26 Jun, based on 55 to 70 days to maturity from the planting date calculated for this location.
How much frost will peas tolerate?
