Because there a “phases” for the election of the chancellor. The first one just failed. We are now in the second one where the parlament can vote again (once or as many times as they like) if Merz isn’t elected after 14 days we will enter phase 3.
The big difference then beeing the needed majority changing from absolute to relative. Merz already had the relativ majority in this first round so it is more or less sure that he will get at least this numbers and will get elected at this point.
In theory this “relative win” could then be vetoed by the federal president but again unlikely with Steinmeier (SPD and big advocate of Union + SPD governments) being in this position.
To add to the other answers: There is Sportractive, not open source but European. Using it for nearly ten years now.
Normally I try using Open Source as much as possible but back then there where not that many options and I really like Sportractive so I stayed.
Nowadays they have some premium features but the main parts are still free. Also at some point a second (blue version) was created, no idea why I use the classic red one.
