How many travel days will be counted for my trip?

Good morning,

I am a student living in Venice, Italy, and I have won an Interrail pass (7 travel days in one month) via the DiscoverEU portal. I’ve found as the first train, the route without change from Venice S. Lucia to Vienna which leaves at 21:48 and arrives the following day at 07:41. The return journey, always without change, with departure from Munich at 23:20 with arrival in Venice S. Lucia the following day at 08:34. Considering these journeys, how many travel days will be counted by the interrail pass? Thank you in advance
