The Romans gave us the first 365 day calendar. It was used then to tell what day it was and when holidays were. Today it is used to tell what day it is and what is happening that day.

A Greek invention is the map. It was created around 610-546bce. The map is still used the same way today as it was used in Ancient Greece, to see were things are.
