Det er lige dumt på dansk som på engelsk. Lav bedre sætninger, please!
Is the baby due?
Why that down vote?
What is that even supposed to mean? Does this sentence sound natural in English?
It would sound natural in response to a question. Depending on what the question is.
Native English speaker here, if I had to say this in proper English, I would probably say 'It is in June', or 'It happens in June'. Hope this helps, from your (maybe) local himbo!
It sounds like det togen er I juni
Bit weird, "det er juni" would probably be ok if you're basically just saying "it's June".
