Learn Danish: I tirsdags diskuterede vi rapporten. - Last Tuesday we discussed the report.

In Danish, adding an -s to a weekday and putting i in front of it (like i tirsdags) is how you say that it happened on that day in the past. It translates to "last Tuesday". If you were talking about an upcoming Tuesday, you would use på and leave off the -s (på tirsdag).

Why is the word order diskuterede vi instead of vi diskuterede?

This is the Danish "V2 rule" in action, where the verb must be the second main piece of information in the sentence. Because the sentence starts with the time phrase I tirsdags, the verb diskuterede must come next, swapping places with the subject vi.

How do we know diskuterede is in the past tense?

Many regular Danish verbs form the past tense by ending in -ede or -te. The dictionary form of the verb is diskutere, and in the past tense it becomes diskuterede (discussed).

I see rapporten translates to "the report". How does that ending work?

Unlike English which puts "the" as a separate word in front, Danish attaches it to the end of the noun. The word for "a report" is en rapport. To say "the report", you move that en to the end of the word, giving you rapporten.
