Even worse, the payday in Denmark tends to be on the last banking day of the month, which means it can vary a lot. Like some years when Easter comes early, payday could be the 27th because banks are closed during Easter. Other months, it’s the 31st.
So even if I could choose a fixed paydate, I would need to change it every month.
Some people are paid bimonthly, every 14 days. So it is definitely a feature that needs some extra work.
