The website is made to show you how much time you have left, to highlight that time is precious. To get this reminder, you have to enter your date through a date picker. This date picker is cumbersome, and makes you waste time. I think this is not a tangential annoyance, but a central one. Those two things are in opposition, and this detracts a lot from the message of this website. If time is so precious, why is my time wasted by an unknown file picker with a foreign interface?
