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.

19 Jun - 10 Jul
Counting back 84 days from your first frost so the crop matures in time.

Held back until the soil is warm enough for this crop. The frost date on its own would say 23 Apr, which is too cold for it to start.
Harvest
10 Jun - 5 Jul
Coriander through the year
Against the frost risk in Kazan
Why these dates
Sow every two weeks from two weeks before last frost. The autumn sowing lasts far longer than any summer one, and in mild climates overwinters.
Takes -5C and grows happily in cool weather. Heat, not frost, is what ends a coriander plant.
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. Coriander are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Kazan.
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 149 days, against 45 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing coriander in Kazan
When should I plant coriander in Kazan?
Aim for 26 Apr - 6 May in an average year. If you would rather not gamble on the weather, wait until 9-19 May - by then frost has finished in nine years out of ten.
Can I plant coriander earlier in Kazan?
Frost is finished by about 23 Apr, but the soil is still too cold. Coriander will not start until it reaches 7°C (44.6°F), and here that is around 26 Apr. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
When will coriander be ready to harvest in Kazan?
Expect to start picking around 10 Jun - 5 Jul, based on 45 to 70 days to maturity from the planting date calculated for this location.
