To state that something happens a certain amount of time before an event, Russian uses the construction за ... до.
| before (in 'за ... до ...') | за ... до |
The Formula
The phrase requires two cases:
- за
- amount of time (Accusative)
- до
- event (Genitive)
| I always arrive half an hour before the departure. | Я всегда приезжаю за полчаса до вылета. |
Since the amount of time is in the Accusative case, masculine inanimate nouns like день (day) or час (hour) match their dictionary forms.
| He warned us a day before the departure. | Он предупредил нас за день до отъезда. |
| I woke up an hour before the meeting. | Я проснулся за час до встречи. |
Feminine nouns like минута (minute) or неделя (week) take standard Accusative endings (-а to -у, -я to -ю).
| It is necessary to warn the clients a week before the premiere. | Нужно предупредить клиентов за неделю до премьеры. |
| The teacher started the lesson a minute before the bell. | Учитель начал урок за минуту до звонка. |
Expressing Approximate Time
To express an approximate amount of time, swap the order of the number and the noun, placing the time noun before за.
For example, за два часа means "two hours before," but часа за два means "about two hours before."
| We arrived about two hours before the flight departure. | Мы приехали часа за два до вылета. |
More Examples
| I managed to order a pizza ten minutes before closing. | Я успел заказать пиццу за десять минут до закрытия. |
| The system sent a reminder two hours before the meeting. | Система отправила напоминание за два часа до встречи. |
| We bought the tickets a week before the trip. | Мы купили билеты за неделю до поездки. |
