Russian: how to tell the time

There are two common ways to ask for the time in Russian:

Который час? - Which hour?

Сколько (сейчас) времени? How many (now) time (slightly less formal)

To answer properly you have to know how Russian numbers are inflected.

Here are some example answers:

Cейчас...

(ровно) три часа. (exactly) three o'clock

десять минут четвертого (три часа десять минут). ten past three

четверть четвертого (пятнадцать минут четвертого). a quarter past three

половина четвертого. half past three

без четверти четыре (без пятнадцати четыре). a quarter to four

без пяти (минут) четыре. five minutes to four

полдень. it's noon

полночь. it's midnight
