Jett Bares said in a recent livestream that this song was about a vacation he took with his family several years back. They toured a mine and learned that, because they didn't have clocks down in the mine, they used candles to keep track of time. They had candles that were designed to last for an hour. So, when one candle burned out, they would know an hour had passed and they would light a new one. Once they had burned through ten candles, they would know the workday had passed and it was time to go home. Thus, these are the "ten candle days" the song references.
