The word for today is – DATE – which refers to the time a thing happens, the day of the month or an appointment or social engagement.
In ancient Rome written letters began with the words – DATA ROMAE – GIVEN AT ROME on the Kalends of March or on the Ides of May etc. Generally letters were dictated by a master to his slave who was educated and knew how to write. The Latin word – DATA – comes from the verb – DO, DARE – which means – TO GIVE. The Romans thus identified from where the letter originated. Therefore, in due process, the word – DATE – slowly came to be used indicating time.
