For example in this run: https://github.com/SuperCoopBerlin/tapir/actions/runs/22879130480/job/66377748408
It could be related to the time at which the test is run (Tuesday evening right after midnight), which would hint at a timezone problem.
Either way I suggest making the test time-independant (use a hardcoded datetime for the monday) and try a few cases to see if we can reproduce it.
