Telling Time and Dates

Telling the time and saying the date are everyday skills, and Icelandic builds both out of pieces you already half-know: cardinal numbers for the clock, ordinal numbers for the calendar. There is one genuine trap — the half-hour points to the coming hour, so hálf níu is 8:30, not 9:30 — and it catches every English speaker. This page drills that explicitly, then walks through quarters, the 24-hour clock, and the ordinal-based date. Number declension itself lives on the cardinals and ordinals pages; here we put the numbers to work.

"It is three o'clock" — klukkan er ...

The word for "clock / o'clock" is klukkan (kvk, "the bell, the clock") — and it carries the definite article already (klukka "a clock" → klukkan "the clock"). To say the time, you start with Klukkan er ... and add the plain cardinal number:

Notice þrjú, not þrír: the clock counts in the neuter, because the understood noun behind the hour is neuter. So "one" is eitt (n), "two" is tvö (n), "three" is þrjú (n), "four" is fjögur (n). From five up the numbers don't change for gender, so fimm, sex, sjö and the rest look exactly as you learned them.

In writing and in quick speech, klukkan is abbreviated to kl. — kl. 7 — and people often drop the verb: just Klukkan þrjú or even Kl. 3 on a notice. To ask the time you say Hvað er klukkan? ("What is the clock?").

The half-hour trap: hálf points to the NEXT hour

This is the single most important thing on the page. In English, "half past eight" means 8:30 — half an hour after eight. Icelandic does the opposite: hálf ("half") looks forward to the hour that is coming, so hálf níu literally means "half (toward) nine" and equals 8:30. You are halfway through the eighth hour, on your way to nine.

This is the same logic as German (halb neun = 8:30) and Danish (halv ni = 8:30), and it is exactly backwards from English. There is no way to reason your way out of it in the moment — you have to drill it until "hálf níu" feels like 8:30.

The hour after hálf is again in the neuter (hálf tvö, hálf fjögur, hálf eitt) for 1–4, because the same neuter "klukkan" sits behind it. Note the accent on hálf — it is not half.

Quarters: korter yfir / korter í

For the quarters Icelandic borrows korter (hk, "a quarter of an hour," from Danish kvarter) and pairs it with two little prepositions:

• korter yfir
  • hour = "a quarter past" (yfir = over/past)
• korter í
  • hour = "a quarter to" (í = to/before)

Here the hours after yfir and í are again neuter for 1–4.

Unlike hálf, these two behave just like English: korter yfir really is "past," korter í really is "to." The trap is only the half-hour.

Minutes: yfir and í for any time

The same yfir ("past") and í ("to") handle any number of minutes. You say the minutes first, then yfir or í, then the hour:

The word mínúta (kvk, "minute") appears here in the plural mínútur. You can drop it when it's obvious (fimm yfir tvö = "five past two"), much as English says "five past two."

The 24-hour clock (formal)

In timetables, official notices, the news, and any written schedule, Iceland uses the 24-hour clock (formal). Here you simply read both numbers as plain cardinals, often joined by núll núll for ":00" or just the bare numbers:

Note that in the 24-hour reading you do not use hálf or korter — you read the digits. So 19:30 is nítján þrjátíu, not hálf átta, in this formal register. In everyday speech (informal) people switch back to hálf átta, korter í, and so on.

Dates are built on ordinals

For the calendar you switch from cardinals to ordinals (fyrsti, annar, þriðji, fjórði, fimmti ...). The date is ordinal + month, and the month name stays lowercase: fjórði júní "the fourth of June," fimmti maí "the fifth of May." The ordinal agrees with the unspoken masculine noun dagur "day," so it sits in the masculine.

To ask and answer:

• Hvaða dagur er í dag? — "What day is it today?"
• Í dag er + [ordinal] + [month] — "Today is the of ."

The day is written as a numeral with a trailing period — 4. — and that period is the ordinal ending: 4. júní is read fjórði júní, never fjórir júní. (The full mechanics of "the dot is the ordinal" are on the ordinals page; punctuation of dates is on punctuation.)

"On the 5th": þann fimmta

To say something happens on a date, the everyday frame is þann + the ordinal in the accusative: þann fimmta "on the fifth," þann fjórða júní "on the fourth of June." Þann is the masculine accusative of the demonstrative, agreeing again with the understood dag "day," so the ordinal goes accusative (fimmta, fjórða).

Years are read as full numbers

Unlike English, which often splits a year into two pairs ("nineteen ninety-eight"), Icelandic reads a year as one whole number (formal/informal alike): 1998 is nítján hundruð níutíu og átta ("nineteen hundred ninety and eight"), and 2024 is tvö þúsund tuttugu og fjögur.

Common Mistakes

Key Takeaways

• Klukkan er + cardinal for the hour; 1–4 are neuter (eitt, tvö, þrjú, fjögur).
• hálf X = X minus thirty — hálf níu is 8:30. It points to the coming hour (like German/Danish, opposite of English). Drill it.
• Quarters: korter yfir (past) / korter í (to); minutes: mínútur yfir / í the hour.
• The 24-hour clock (formal) reads the digits — nítján þrjátíu = 19:30, no hálf.
• Dates use ordinals: fjórði júní (4. júní); "on the 5th" is þann fimmta (accusative).
• Years are read as one full number: nítján hundruð níutíu og átta = 1998.
