You might be the right anon to ask a couple of basic (aka 100 not 101 level) clock questions since most ClockFags give you crickets when you ask for details behind their work.
1) How were the dates that are on the clock determined? I assume based upon Q drops/confirmations correct?
2) Mirror: Why was the 180 degree mirror (aka straight across clock to other side) chosen over the kind of mirroring where you match what the clock looks like in an actual mirror (aka 6 stays 6, but 7 mirrors to 5, 8 to 4, etc.)?
