Can a civil wedding be performed on a Sunday in Krakow?

I am an American who will be marrying a Polish woman in the city of Krakow. We have conflicting information.
Can a civil marriage be performed on a Sunday? Is there an official equivalent of a
justice of the peace who can legally perform such a ceremony?

Yes, the ceremony is performed 7 days a week. But if you don't have Plish citizenship you need a permission from the Polish court to marry and that takes about a month, then you have to wait a month for a date. The ceremony can be performed by someone else who is entitled to it.
