Telling the Time in Russian: полшестого, без четверти, 19.25

Russian tells the time by two completely different systems, and knowing which one a situation calls for matters as much as the grammar itself. Everyday, spoken time-telling counts forward into the hour ahead and uses без (without) for the back half of the hour. Timetables, announcements and anything official use a plainer 24-hour system built from the ordinary number-and-case rule. Both are on the Higher tier of the Pearson Edexcel GCSE specification.

One hour, worked in full

Seeing every stage of a single hour laid out together makes the pattern click faster than any rule on its own. Here is five o'clock through to six, minute by minute at the landmarks:

Read down the middle column and the hinge is obvious: everything up to half past reaches forward and grabs the sixth hour early (шестого); everything after half past counts backward from the six that is about to arrive (шесть). Nothing about five o'clock itself, пять, appears anywhere in the 5:05 to 5:50 rows at all, which is exactly the part English speakers keep expecting and not finding.

The clock face splits the same way, at the half hour:

On the hour: the easy part

Сейча́с пять часо́в (it is five o'clock) uses the cardinal number plus the case it demands, exactly as Russian numbers already covers. Nothing new happens on the hour itself; the interesting grammar starts the moment the minute hand moves.

Minutes past the hour: naming the hour you are heading into

Here is the part that surprises English speakers most. From just after the hour up to the half hour, Russian names the coming hour, not the one just started, because it thinks of that stretch as part of the hour ahead:

The structure is minutes, cardinal + мину́т (in whatever form the number demands, exactly as when counting anything: одна́ мину́та, две мину́ты, пять мину́т) + the coming hour, as an ordinal, in the genitive. Шестого is the genitive of шестой (sixth); every hour works the same way, пе́рвого, второ́го, третьего and so on, once you are inside the hour leading up to it.

Quarter past uses че́тверть (a quarter) in place of a minute count, in the nominative, with the coming hour still genitive.

Half past: половина, or полшестого

Half past uses полови́на (half) plus the same genitive ordinal hour, and it is so common that it is almost always shortened into a single word, пол- plus the hour:

Пол fuses directly onto the front of the hour word with no space, which is why the short form looks like one word rather than two. Both forms mean exactly the same thing; the short one is simply what people actually say.

Minutes to the hour: без plus the genitive

Past the half hour, the system flips. Instead of counting minutes into the coming hour, Russian counts minutes away from it, using без (without), which takes the genitive:

The structure is без + minutes, genitive + the coming hour, left in its plain, uninflected form. Десяти́ is the genitive of де́сять; че́тверти is the genitive of че́тверть. The hour at the end, шесть, is not put into any further case: it is simply being named, the way it would be if you read a clock face and said the number out loud.

The 24-hour clock: timetables and announcements

Formal, written and spoken-announcement time (train times, opening hours, schedules) drops all of the above and uses the plain number-and-case system instead, exactly as Russian numbers teaches for any counted noun:

The structure is hour, cardinal + часо́в + minutes, cardinal + мину́т, with часо́в and мину́т both taking whatever case the last word of each number demands. Во́семь and девятна́дцать both trigger the genitive plural часо́в (eight is five-and-up; nineteen is a teen-style number, always genitive plural); три́дцать and два́дцать пять both trigger the genitive plural мину́т for the same reason.

In casual speech the words часо́в and мину́т are often simply dropped, leaving just the digits read aloud, the way English drops o'clock and just says the numbers.

Morning, afternoon, evening or night: no am and pm

Russian has no equivalent of am and pm. Instead, a clock time is followed by the genitive of the part of the day it falls in, whenever the hour alone would be ambiguous:

• Пять часо́в утра́. - Five o'clock in the morning.
• Пять часо́в ве́чера. - Five o'clock in the evening.
• Час но́чи. - One o'clock in the morning (the middle of the night).

The boundaries are approximate and cultural, not exact clock cutoffs: an early riser might call six утра́, a night owl might still call two но́чи rather than утра́. The genitive case here is the same one covered in the genitive case article, used because the phrase is short for hour of the morning, and it applies whichever time system, informal or 24-hour, is being used.

The 24-hour clock itself needs no утра́/ве́чера at all, since девятна́дцать часо́в already says 19:00 without ambiguity, which is one reason official announcements prefer it.

At what time: в котором часу, во сколько

Asking when something happens, rather than what the time is now, needs a different question:

Both are answered with в plus the time:

So a full sentence with the без shape reads: Уро́к начина́ется без че́тверти шесть.

Asking the time

Two everyday questions, both used constantly and interchangeably:

Either is answered with whichever of the shapes above fits the actual time: Пять часо́в on the hour, Полшестого at the half hour, Без че́тверти шесть approaching six, Девятна́дцать часо́в два́дцать пять мину́т reading off a departure board.

Mistakes English speakers make

What to do next

1. Drill the switch at the half hour until it is automatic: up to and including half past, the coming hour, genitive, ordinal; after it, без plus genitive minutes plus the plain coming hour.
2. Practise saying full hours on the 24-hour clock too, since timetables and announcements will not wait for you to translate.
3. Russian numbers and the case after each underlies both systems, and the Russian course drills real clock times in its daily-routine material.
