Hi,
As an unemployed unemployment benefit recipient, you have the right to take a holiday like everyone else. As you say your self you can off course not get unemployment benefits in the holiday period.
However you must remember to report the holiday to both the Jobcenter (Jobnet.dk) and your A-kasse.
The job center must be notified of your holiday no later than 14 days before the holiday starts. The A-kasse must be informed at latest on the first day of your holiday.
You must use your 2 year period with Unemployment benefits (“dagpenge”) within a 3-year reference period.
Best regards,
Anders Weber, A-kasser.dk
