Distinguishing date (years): BC/AD (in visjs timeline and elsewhere)

[Miroslav Kalous]

Hi, everyone,

I have encountered a problem when using vis.js timeline plugin (which I love and am indebted to its author). But I guess the problem goes beyond this plugin and concerns date formating more generally.

The timeline plugin works with two types of date formating: TW5 date format and moment.js Parse string+format. I haven't found any info about the support for "after/before christ" years formating in these two formats. Does it mean that neither TW5 nor moment.js Parse work with BC dates? It seems so to me but I want to make sure so that is why am asking here.

Practically, it means that every timeline I make starts with the year 0 or after. It never goes back BC.

Thanks everyone for any tips or workarounds,

Mira

This is, at core, a javascript problem.  You may wish to read the following links to decide best how to proceed:

So, there are solutions, but I don't know if that will help you with vis.js.
