Adjective in Genitive Case

The Usage of Genitive Case in Russian Numbers

We already know the change in suffix of nouns for Genitive case. Now, we are going to talk about the situations that could use Genitive case in Russian numbers. The change for numbers is based only on masculine gender. There are several questions that refer to it.

1. Точная Дата ‘The Accurate Date’
   The accurate date could be used in three periods (past tense, present tense, and simple future). The answer for the question of Какое сегодня число? is using the ordinal numbers for neutral gender in Nominative case. Meanwhile, the name of month and year use the Genitive case. For example:
   – Какое сегодня число? ‘What is the date today?
   Cегодня тридцать первое декабря две тысячи семнадцатого года. ‘Today is December 31st, 2017.
2.  Дата в письме ‘The Date in a Letter’
   For examples:
   – Labeling the date on the letter:
   3/III-95 г or 3 марта 1995 г ‘3 March of 1995’.
   (третьего марта тысяча девятьсот девяносто пятого года ‘third March of one thousand nine hundreds ninety five).
   – Calling the date of the letter:
   Письмо от третьего марта тысяча девятсот девяносто пятого года ‘A letter from third March of one thousand nine hundreds ninety five’.
3. Точная Дата События ‘The Accurate Date of Event’
   For examples:
   – Когда была принята Конституция Российской Федерации? ‘When was the Constitution of the Russian Federation accepted?’
   Конституция Российской Федерации была приняиа двенадцатого декабря тысяча девятьсот девяносто третьего года.
   ‘The Constitution of Russian Federation was accepted in December twelfth of one thousand nine hundreds ninety three.’
   – Когда ты возвращаешься? ‘When do you return?’
    Я возвращаюсь двадцатого фебраля. ‘I return on twentieth February.’
   – Когда вы родились? ‘When were you born?’
   Я родилась двадцатого фебраля тысяча девятьсот девяносто пятого года. ‘I was born on twentieth February, one thousand nine hundreds ninety five.’

When you answer the question of ‘Когда?’, the ordinal numbers which remark the accurate date, are used without preposition.
