In Germany, “runde Geburtstage” are special. They are those birthdays that end with a “zero” – like 30, 40, 50, 60 etc. Leo.org calls them “big birthdays” or “significant birthdays”. I’ve also heard the term “milestone birthdays” before. But not in England, strangely enough.

I quite like to call them “important” or “special birthdays”. But then I wonder, aren’t all birthdays important and special?

In German, we even have a verb for these birthdays. It’s “nullen” which literally means¬†“to zero”. Thanks, Deutsche Welle, for reminding me.
