День отлёта день прилёта
За день посчитаю
Нам предписан нашим веком
Скоростной режим.
I'm not sure that my translation is the appropriate.
Day of taking off, day of landing
a) In one (the same) day /Both the same day; I consider or
b) After a day I consider
That our century has determined for us
A rapid way of living (regime) (Active voice)
Or
That a rapid regime
Has been determined for us by our century (Pasive voice).
The matter is not if active or passive, but if the meaning is correct.
Thank you.
