Alkuperäinen teksti - Englanti - This week

More info is needed for Finnish translation:
-tämä viikko = this week ((is boring)) (basic form but doesn't work with example given)
-tällä viikolla = (nothing happened) this week
-tämän viikon =(top favorite of) this week
-lots of others

So the question is that is this going to be used on other contexts than in the given example or not? If yes then I don't think this can be translated easily.

The only context will be "top favorite of this week"
