Right, here it is:
Sunday early afternoon isn't a good time for me, considering RL and such things. Friday is more like it, and I can stay up for some more time too, I just felt the play to become really slow, so I thought that the others are tired too. Anyway, I won't be able to attend on 20th, as I will have a test on 21th (stupid 1st of May, I have to go to school on Saturday...). But anyway, I would say Friday is better for me, 13-14 CET would be too early for me, but if it would mean more players and everyone else would want that, then I will try to make arrangements.
