"우리는 생일이 똑같아요!"

Translation: Our birthdays are the same!

[Staszek456]

같다 - same or very similar; 똑같다 - exactly the same

[Al-Asmawi]

yet "exactly the same" isn't an accepted answer here

[BobPancakes]

I would argue 같다 is "similar" (not same) and 똑같다 is "same".

"Exactly the same" would require a similar modifier like 완전히 or 굉장히 or something.

[oee16]

I agree.

같다 = alike, similar (but not the same one.) ~ doubles

똑같다 = be exactly alike, identical (but not the same one.) ~ clones

바로 같은 or 정확히 똑같은 = the very same (one and the same)

[Peter474567]

Why not 우리의

[BobPancakes]

It's more like "we have the same birthday" rather than "our birthday is the same".

[tsunbae]

think of it as "as for us, the birthdays are the same." korean language constructs don't map one-to-one to English

[oee16]

"We share the same birthday" is another way to put it.

[haobubble]

Would this imply the year as well, or just the day? Or would that be based more on context/clarification in the situation?

[oee16]

Like in English, 생일 ( =birthday ) is only about day & month.

It is not the same as 생년월일 ( = Date of birth ) which includes the year of birth.
