"Today is my uncle's birthday."

Translation: 今天是我叔叔的生日。

In normal conversation 的 isn't used for relatives or family （我叔叔，我媽媽，我爸爸）

[Charlotte775797]

I agree. I'm a native speaker and this is driving me nuts!

There is only one 的 character on the android ap and I used it as follows; 叔叔的生日.

I placed 的 incorrectly at: 今天 是 我的 叔叔 生日.
In the above, could someone explain what it means or why it is incorrect.

You can leave it out for family members where you have it, but it is apparently required for birthdays

I wrote 大姨夫 for uncle (specifically the husband of my mum's eldest sister) and it was rejected. Surely it should work for any kind of uncle?!
