"Innen mandag kommer vi til å ha lært mye."

Translation: By Monday we will have learned a lot.

Does 'innen mandag' here mean 'by Monday' or 'on Monday itself'?

[grydolva]

You should be finished learning before the Monday begins. By Monday.

On Monday itself = på mandag. Or during (the) Monday = i løpet av mandag/mandagen.
