as I understand your previous comments, then you started on a 2-year dagpenge period on 1st of July 2018. If this was your first-time unemployment period, then the dagpenge right was earned either by fulfilling the income-requirement or as a graduate.
You have until July 1, 2021 to use 3.848 hours with dagpenge. As long as you have hours (from the 3.848) left, your A-kasse will not look at all on how much you you have worked since July 1, 2018.
However working hours can be used to extend the 2-year period. 1 day of work gives you 2 days more with dagpenge. You can maximum extend with 1 year, so will have dagpenge for 3 years.
If you by this way extend your dagpenge period, then also the reference-period will be extended (1 day of work exends the reference period by 3 days). However you can maximum extend the reference-period by 1,5 year, so it will be 4,5 years.
The total maximum benefit period can thus be 3 years (corresponding to a total of 5,772 hours) within a period of 4 years and 6 months (corresponding to a total of 54 months).
Only if you want a second 2-year period with dagpenge, then the A-kasse will look on how many hours you have registered since July 1, 2018.
Because this will not be a first-time unemployment period, then you need to meet the working-requirement (instead of the income-requirement). Therefore the A-kasse will look if you have worked at least 1.924 hours. If you have, then you will get a new 2-year period, that must be used within a new 3-year reference period.
