[Feature Request] Support for BC dates #156

Open

Description

@mburnett8

I'd like to make historical timelines that extend before year 0 extending to 100K+ years. The visualization does not appear to support this yet.

    I found a workaround, definitely not ideal, but you can do:

    4500 BCE: start sumarians
    id: start_sumarians
    
    after !start_sumarians 2600 years: Sumarians  #keep
    
    3100 BCE: start egyptians
    id: start_egyptians
    
    after !start_egyptians 3070 years: Egyptian Dynasties  #keep
    
    27 BCE: start romans
    id: start_romans
    
    after !start_romans 422 years: Unified Roman Empire  #keep
    

    And filter on the keep tag to hide the start events:

    For the >100k BCE you could use (though even less ideal):

    99999 BCE: year 99999
    id: year_99999
    
    before !year_99999 50000 years - 100000 years: some  period (200k-150k BCE) #keep
