Is my driving license valid???

hi,
i have a cuban driving license and I wonder if someone could tell me whether it´s valid here, for how long and what is the best way to convert it(if possible)or get a new one, thanks

You should properbly try to write an e-mail to the local policestation. They should be able to answer your question.
Yoy can find the nearest on www.politi.dk it is possible to get the site in english as well.
Some driverslicens are fine in Denmark whereas others are only valid for about 3 months.

This is in danish only -

It is slightly amusing that the information page on "From foureign to danish driver licens" is only available in danish.
From the law: https://www.retsinformation.dk/Forms/R0710.aspx?id=2405#K12
There is a difference whether you are here permanently or on a temporary visit. If you are on a temporary visit then you are probably ok. There are a few exceptions where only one seems to be important. If your licens is typeset in something else than roman letters then you need an official translation (to danish, french or english) granted in your home country. I suggest mailing a tourist information. For instance http://www.visitcopenhagen.dk/
If you in for a permanent stay you must go to the town hall not the police. You need your passport, medical report, driver licens, picture of yourself (following strict rules) and a valid document of residence. (danish or EU-citizen) You also need to take a driving test, so I suggest that you meet up at the local town hall and hear them out.
