I'm trying to add the festivities for 2020 to my normal calendar in Service Desk but even though I'm seeing the correct date selected in the box, it is registrered as the prior date whenever I click on the "Add" button.
I'm pretty puzzled. Of course I've resorted to simply select one day later than the day I actually want but I was hoping that maybe someone has encountered this behaviour before and already has a better solution ready to share...
Thanks in advance 
EDITED: In my experience doing this, once populating every festivity and testing a couple of extra test dates, it has never failed for the 1st of january and a couple of times it has worked as intended. Honestly... it would be better if the behaviour would have been allways the same, even if wrong.
