The Romans knew about festivals - they had lots of genuinely Roman ones, but as their empire grew they also adopted the festivals and gods of their conquests. Often it was just an excuse for a booze-up or barbecue - please feel free to celebrate in any ways that please you.
It may not always be possible to be on-air for particular Tempus Romanus events.
List of festivals
Of course, there are major inconsistencies when relating Roman dates to modern ones, so these dates are all approximate - it didn't really matter to the Romans. We will also add 'specials' whenever we can. Phoenix & Aries ARCs aim to be on-air for these celebrations (subject to conditions on HF & VHF). See the Aries & Phoenix websites for latest information
