One way to say that you have a birthday in Swedish is to use the verb fylla (to fill up, load, pack). For example:
– Jag fyller i april = My birthday is in April*
– Du fyller år i morgen = Tomorrow is your birthday
– Han fyller nämligen år i dag = It’s his birthday today
– Hon fyllde 40 år i går = She was 40 years old yesterday
Birthday in Swedish is födelsedag [ˈføːdɛlsɛˌdɑːɡ /ˈfœlsɛˌdɑː(ɡ)], and Happy Birthday is Grattis på födelsedagen. Födelsedag comes from födelse (birth) and dag (day). Födelse comes from föda (to feed, give birth), which is related to the English words food and feed; and -else (a suffix that makes verbs into nouns).
*Could you also say Min födelsedag är i april (My birthday is in April)?
