Starting now the Berlin Wall has been down longer than it was up:
Construction began 13-Aug-1961. Demolition began 9-Nov-1989. 10284 days. 5 January 2018 is 10284 days since the wall began coming down.
Ugh. You're right. I goofed and did 09 for August instead of 08. Ah, well... That's what I get for doing it quickly on the train.
