Decades and approximate age (-erne)

Talking About Decades

To refer to specific decades, like "the 1970s" or "the 1980s", Danish uses the definite plural suffix -erne. When writing the year as a number, attach the suffix using an apostrophe. Just like in English, this is typically paired with the preposition i (in).

In the 1970s, that style was popular.
I 1970'erne var den stil populær.
In the 1950s, women loved the silhouette because it reflected elegance.
I 1950'erne elskede kvinder silhuetten fordi den afspejlede elegancen.

Approximate Age

You can use this exact same structure to describe someone's approximate age, such as being "in their twenties" or "in his forties." Add the definite plural suffix directly to the spelled-out Danish number for the tens (e.g., tyve becomes tyverne, fyrre becomes fyrrerne). Again, use the preposition i.

The creator was in her twenties when she created the trend.
Skaberen var i tyverne da hun skabte trenden.
My grandfather was in his forties when that trend became popular.
Min bedstefar var i fyrrerne da den trend blev populær.
Men in their sixties participated in the rebellion, right?
Mænd i tresserne deltog i oprøret, ikke også?
