How to interpret austrian sauna timetables

I can't read German language and the only information I've found to visit the historic Jörgerbad pool is in this language. The Google translation is quite useful, but there is something I can't understand. In this page (english translation here) the Wednesday say "9 to 9:30 pm (Women and mixed)". What does it mean? Thursday in example it's also confusing to me because at the same time it's "men" and "women" from 9 to 4pm (unless there are separate saunas for each gender that day).

My idea is to visit this swimming pool with my girlfriend and we prefer to stay together, so we want to choose the right day and time.
