Whichever spelling local authorities choose, most newspapers and public institutions will accept it.
It is notable that the "Aa" spelling has been in use the longest.
"Aa" was also used by some major institutions between 1948-2011 as well, such as Aarhus university (AU) or the largest local sports club, Aarhus Gymnastikforening (AGF), who have never used the "Å"-spelling.
Some Danish cities resisted the new spelling of their names, notably Aalborg and Aabenraa.
Århus city council explicitly embraced the new spelling, as it was thought to enhance an image of progressiveness.
In 2010, the city council voted to change the name from "Århus" to "Aarhus" to strengthen the international profile of the city. Certain geographically affiliated names have been updated to reflect the name of the city, such as the Aarhus River, changed from "Århus Å" to "Aarhus Å".
