When in Rome

We are going on vacation and will be visiting Paris, Amsterdam and Rome. I’ve never been to Rome so have been doing lots of reading especially about Julius Caesar. Not surprisingly there are many things I didn’t know, for instance: the sundials they used kept daylight time divided into 12 hours. That meant that an hour in the summer was longer than an hour in winter!!!

By Caesar’s time there was a discrepancy between the Roman calendar year and the solar year. His solution was to extend the year 46 BC to 445 days and then fix future calendars to 365 days, with an extra day in February every fourth year. Obviously a good solution since it’s what we still do today!
