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 direct
2-23 Jun
Held back until the soil is warm enough for this crop. The frost date on its own would say 16 May, which is too cold for it to start.
Harvest
26 Aug - 30 Sep
Soybeans through the year
Against the frost risk in Podolsk
Why these dates
Sow two weeks after the last frost into warm soil. Varieties are grouped by maturity for a given latitude, and a variety from the wrong group will either flower far too early or fail to finish at all - this matters more with soybeans than with almost any other crop.
No frost tolerance. Killed at 0C at both ends of the season.
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. Soybeans are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Podolsk.
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 158 days, against 85 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing soybeans in Podolsk
When should I plant soybeans in Podolsk?
Aim for 2-23 Jun in an average year. If you would rather not gamble on the weather, wait until 1-22 Jun - by then frost has finished in nine years out of ten.
Can I plant soybeans earlier in Podolsk?
Frost is finished by about 16 May, but the soil is still too cold. Soybeans will not start until it reaches 15°C (59°F), and here that is around 2 Jun. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
When will soybeans be ready to harvest in Podolsk?
Expect to start picking around 26 Aug - 30 Sep, based on 85 to 120 days to maturity from the planting date calculated for this location.
How much frost will soybeans tolerate?
No frost tolerance. Killed at 0C at both ends of the season.
