 *The leap years that were actually observed between the implementation of the Julian calendar in 45 BC and AD 8 were erratic, so we use a proleptic Julian calendar for anything before AD 8. Basically we just make every 4th year a leap year regardless of what happened in reality. In the Common era leap years are 4 AD, 8 AD, 12 AD and so on. Leap years before Common era are: 1 BC, 5 BC, 9 BC and so on.
-*Year 46 BC (the year of Caesar’s calendar reform) had 445 days in it. A bunch of preceding years were much shorter than a usual year. In general Roman calendar before the reform had shorter month lengths and used and intercalary month instead of an intercalary day. The Timeline ignores all that. We just use normal 356 and 366 day years for all the years BC. This can be changed with future updates if such need ever arises.
