No, for being eligible for unemployment benefits ("dagpenge") you only have to have been member for 1 year with an A-kasse, you do not need to have paid contribution to A-kasse for 7 years.
The new requirement from January 2019, states that you must have stayed in Denmark or another EU/EEA for 7 out of last 12 years to be able to collect Unemployment benefits. The requirement is not about that you must have paid to A-kasse for some years, it is about that you must have stayed in DK or another EU/EEA country for some years.
However the new rule will, according to the law-suggestion, be phased in over a 3-year period, so the requirement will be:
- in 2019 the requirement is five out of the last twelve years
- in 2020 the requirement is six out of the last twelve years
- in 2021 the requirement is seven out of the last twelve years
The requirement must be meet at the time you apply for Unemployment benefits ("Dagpenge").
So, if you come to Denmark after have been living in a non-EU/EEA country for some years, it propably gives no meaning to join A-kasse before about 1 year before you can fulfill the requirement of stay (5/6/7 years out of the last 12 years).
