Calendar boy? (3)
This clue is a double definition.
'calendar' is the first definition.
(Julian calendar is an example)
'boy?' is the second definition.
(Other definitions for julian that I've seen before include "Calendar devised by Caesar" , "Associated with Caesar" , "Sort of date" , "boy" .)
'boy?' is the definition.
(boy's name)
I don't understand the remainder of the clue.
Can you help me to learn more?
