Advent of Code Day

I'm participating our company's Advent of Code competition for the fifth year in a row this year. While looking through my old times, I noticed that I never went to bed without first solving the night's puzzle. Here's a graph of how late after midnight I was up over the years.

The 4:39 spike in 2019 was the worst. You had solve a maze with keys and doors by moving a robot the fewest steps in Part 1. In Part 2, the maze was divided into four isolated quadrants and there were four robots. After solving that monstrosity, I got in the car and drove straight to the office for another day of proposal writing.

I'm currently in 2nd place. You can keep up with my daily progress this month on this competition leaderboard (which I also run).
