Why is the day written like четвёртое and not четыре?

The day of the month is an ordinal number agreeing with the neuter noun число, so it takes the neuter nominative ordinal form: первое, второе, четвёртое, двадцать пятое, and so on, never the plain cardinal.

Why is the month in the genitive case?

Russian expresses 'of June' with the genitive: июня, not июнь. The construction is literally 'the fourth of June', so every month appears in its genitive form (января, февраля, июня, декабря).

Why does the year end in шестого года?

The year is an ordinal in the genitive case because it answers 'of which year'. Only the final element becomes the ordinal genitive, so 2026 reads две тысячи двадцать шестого года, with the leading parts as cardinals.

What date range is supported?

The tool handles years from 1000 to 2999, covering one-thousand and two-thousand year prefixes (тысяча and две тысячи). This spans all realistic historical and contemporary dates.

Can I use the output in formal documents?

Yes. This long-hand form is the standard way dates are written out in Russian contracts, certificates and official letters, where spelling the date in words reduces ambiguity and tampering.

Russian writes dates out in a specific grammatical pattern that trips up learners: the day is an ordinal, the month is genitive, and the year is an ordinal genitive ending in года. This tool produces the exact spoken and written form from any date you pick.

How it works

A date such as 04.06.2026 is built from three pieces:

Day — neuter nominative ordinal: 4 becomes четвёртое (agreeing with число).
Month — genitive case: June becomes июня (“of June”).
Year — ordinal genitive: 2026 becomes две тысячи двадцать шестого года.

Only the final magnitude of the year takes the ordinal genitive ending (шестого); the parts before it stay as cardinals (две тысячи двадцать). When the year is a round thousand the whole thing collapses, e.g. 2000 becomes двухтысячного года.

Example

04.06.2026 -> четвёртое июня две тысячи двадцать шестого года
01.01.2000 -> первое января двухтысячного года
31.12.1999 -> тридцать первое декабря тысяча девятьсот девяносто девятого года

Notes

The genitive year form is what you say when reading a date aloud or signing a document (“today is the fourth of June of the two-thousand-twenty-sixth year”). Use the Copy button to drop the phrase straight into contracts or certificates, where dates are routinely spelled out in full to prevent alteration.
