Can I use past tense when asking about someone’s birthday?

1. It’s like asking “What’s your year of birth” vs “What was your year of birth”. It hasn’t changed, so it’s weird to use past tense. Note that 生まれ is a noun, if you used the verb 生まれる then it would be okay to say 何年生まれましたか

2. I just go like I’m interrogating them. 「おい、生年月日？」
