This year the two Seders are on Friday and Saturday. My understanding (please tell me if I'm wrong) is that the normal Shabbat blessings are done before the Seder on Friday night, and the normal Havdalah blessings are done before the Seder on Saturday night.
Does this mean that one drinks five cups of wine each night? Or is the wine omitted from the Shabbat/Havdalah ceremonies, leaving just the normal four for the Seder?
(I see this somewhat answered in https://judaism.stackexchange.com/a/56319/28527 , but that primarily says that your Haggadah will explain, but none of mine do, so I'm struggling to interpret)
