This weekend sees the first ever Festival of Time happening in Waterford.
The Festival will see the world's best horologists descend upon Waterford City with a host of events planned at the Museum of Time.
The measurement of time began with the invention of sundials in ancient Egypt, but the format of time we use today was not developed until Medieval Times by Benedictine monks.
So we thought it was about time (get it!) we tested you on all things to do with time.
Have a go and don't forget to share on your socials.
