When does Italian use primo?

Italian uses the ordinal primo only for the first of the month, written il primo giugno. Every other day uses a plain cardinal number such as due, tre, or trentuno, with no il required.

How are Italian years written in words?

Italian years are written as a single compound word with no spaces, so 2026 is duemilaventisei. The components duemila, venti, and sei join directly, which is standard Italian number spelling.

Why does ventuno drop a vowel?

Italian elides the final vowel of venti, trenta, and similar tens before uno and otto, giving ventuno, ventotto, trentuno, and trentotto. This vowel-dropping rule applies whenever those compounds are formed.

Are Italian months capitalised?

No. Italian month names like gennaio, giugno, and dicembre are written in lower case unless they begin a sentence. The tool keeps months lower case, matching standard Italian orthography.

Writing an Italian date in full words follows clear rules: the first of the month is the ordinal primo, every other day is a cardinal number, and the year is a single compound word with no spaces.

How it works

The phrase is built as day + month + year:

day:   1   → primo (the only ordinal day, usually "il primo")
       2–31 → cardinal: due, tre … trentuno
month: 1–12 → gennaio, febbraio, marzo … dicembre (lower case)
year:  compound word with no spaces, e.g. 2026 → duemilaventisei

Italian elides the final vowel of tens before uno and otto, producing ventuno, ventotto, trentuno, and trentotto. Numbers like 23 become ventitré with a written accent on the final é.

Example and notes

01/06/2026 becomes il primo giugno duemilaventisei, while 04/06/2026 becomes quattro giugno duemilaventisei. Note that cento and mille join without spaces too, so 2025 is duemilaventicinque and 1999 would be millenovecentonovantanove, always written as one continuous word.
