Date question

Good evening everyone,
I have a question in regards to date expression in Russian.

С десятого мая по пятнадцатое - from the tenth to the fifteenth of May inclusive.

In a book it says с + gen and по + acc.
Then why use пятнадцатое instead of пятнадцатый?

Is it because to make it match to число? Please help!! Thank you!!!

Hi. Yes, we use neuter gender just in order to match with the neuter noun “число”.
So, it would be somehow like “по пятнадцатое [число - acc, neuter] мая [месяца - gen, masculine]”.

Ahhhhh It makes sense now! Thank you!!! Happy new year!

Hi @keepthafaith,

Пятнадцатое is neutral gender (as число). That’s why -ое.

Best of luck
Pavel

Thank you.
