Questions & Answers about Kad je vani hladno, puhnem u dlanove.
Yes. Kad and kada both mean when.
- kad is more common in everyday speech
- kada can sound a bit more formal, careful, or emphatic
So Kad je vani hladno and Kada je vani hladno both work.
Because kad means when / whenever, while ako means if.
In this sentence, the idea is a normal, repeated situation:
- Kad je vani hladno, puhnem u dlanove. = Whenever it’s cold outside, I blow into my palms.
If you said:
- Ako je vani hladno, puhnem u dlanove.
that would sound more conditional: If it’s cold outside, then I blow into my palms.
Both are possible in some contexts, but kad is very natural when talking about something that regularly happens.
