#ordinal

First of all, when do you use this?

According to my textbook, “time when”, so: the event was on [this date] or the party will take place on [that date]. This is when with the day and the month.

With day, month, and year, it still has no prepositions. So, the answer to the questions: when were you born and when did he die.

How to form the numbers? Take the number in nom, drop ending, and add ого, ьего (soft), ей (fem), or их (plural).
