True enough!

At one point I considered doing logs of fractions so that I could extend the Log of History to years B.C.(E), but it gets increasingly difficult to find significant events known to have happened in those years. I also thought about doing a separate timeline for decimals, eg 1000xlog(15.5) = 1190, when Emperor Frederick Barbarossa drowns while leading the 3rd Crusade to Jerusalem, and 1000x(19.5)=1290, which was an eventful year in the life of England's Edward I: he passed a law kicking all the Jews out of England, passed a law that stopped land from passing into the hands of the Catholic church after someone died, and his wife Eleanor of Castile died.

However, it will take me a while to get to 2017 using whole numbers, so it's a decision that will wait until I get there!
