Time & Dates ​

Clock time, days, months, and how to say when.

Telling the clock ​

To ask the time: Wie spät ist es? or Wie viel Uhr ist es? The answer is Es ist …

Everyday German counts toward the next hour. The tricky one is halb: "halb drei" means half an hour before three = 2:30, not 3:30. Think "half on the way to three."
TimeEveryday GermanMeaning
3:00drei Uhrthree o'clock
3:15Viertel nach dreiquarter past three
3:30halb vier"half to four" = 3:30
3:45Viertel vor vierquarter to four
3:20zwanzig nach dreitwenty past three
3:40zwanzig vor viertwenty to four
Official/formal contexts (timetables, TV) use the 24-hour clock, read straight: 14:30 = "vierzehn Uhr dreißig." No halb/Viertel.
Es ist halb neun.
It's 8:30. (half on the way to nine)
Watch out: halb neun = 8:30, not 9:30.
Der Zug fährt um 16:12 (sechzehn Uhr zwölf).
The train leaves at 16:12.
Timetables use the 24-hour clock, read as "… Uhr …".

um, am, im — the three time prepositions ​

Three little words cover most "when" answers, and they don't translate one-to-one with English:

um + clock time — at: um acht Uhr (at eight)
am + day / part of day — on/in: am Montag (on Monday), am Morgen (in the morning)
im + month / season — in: im Mai (in May), im Sommer (in summer)

Exception: in der Nacht (at night) and um Mitternacht (at midnight).
Der Kurs beginnt um neun Uhr.
The course starts at nine o'clock.
um is used only with clock times.
Am Freitag habe ich frei.
On Friday I have off.
am = an + dem, used with days and parts of the day (am Abend).
Im Dezember schneit es oft.
In December it often snows.
im = in + dem, used with months and seasons (im Winter).

Days, months, seasons ​

Days and months are all maskulin (der Montag, der Mai), so they take am/im (from dem). Seasons are maskulin too (der Sommer).

Montag, DienstagJanuar, Februarder Frühling (spring)
Mittwoch, DonnerstagMärz, April, Maider Sommer (summer)
Freitag, SamstagJuni, Juli, Augustder Herbst (autumn)
SonntagSeptember … Dezemberder Winter (winter)

Dates ​

Dates use ordinal numbers (first, second, third…), formed by adding -te (1–19) or -ste (from 20) to the number, written with a dot: 1. = erste, 3. = dritte, 20. = zwanzigste. A few are irregular: erste (1st), dritte (3rd), siebte (7th).

To say "on the …th," use am … -ten.
Heute ist der erste Mai.
Today is the first of May.
der erste = the 1st (Nominativ). Written "der 1. Mai".
Ich habe am dritten Juni Geburtstag.
My birthday is on the third of June.
am dritten = on the 3rd (am + ordinal + -en). Written "am 3. Juni".
