B.C and A.C dates

[cgrillo98]

Hello, does anyone know if it is possible to add B.C and A.C dates in the timeline?
Thank you.

@cgrillo98 unfortunately, no--it isn't supported out of the box.
The timeline is built using Liquid (which does not seem to support BC dates in date parsing) and only does very basic parsing of dates (manually, not using Liquid's limited date parsing abilities). The advantage of this is that it avoids a lot of errors that come up from trying to parse date fields (is forgiving of metadata inconsistency) and the timeline can be quickly reused for other types of visualizations (i.e. not dates)--the disadvantage is that it isn't very smart...

That said, you could customize the timeline layout to work with BC dates--there are a few different approaches possible depending on your collection contents and aims. This might involve creating a new metadata field that can be used to correctly sort the items internally. For example, your "date" field might have a value like "300 BCE", with a "sort_date" field of "-300" (with year only). We would then tweak the Liquid logic in the timeline to sort using the "sort_date" values, and add logic to display "300 BCE" for negative numbers and "300 CE" for positive numbers.

@cgrillo98 I think you "approved" my recent pull request, but didn't merge it. Here is the github documentation for merging PR. Let me know if that works!

[cgrillo98]

Yes! thx.
I can´t merge one of te pulls because there is a conflict on the timelinejs.json

@cgrillo98 your site still isn't building correctly on GitHub Pages--> the issue is with using the rgb values in "_sass/_custom.scss". The way you have them written, like background-color: rgb(0 0 0 / 31%) !important; actually works in newer versions of SASS, but the version of SASS used by GitHub Pages is old! These values cause an error, so you site is not rebuilt.

Ok,thank you.
Now it works perfectly!
