I see Asia/Kolkata in the list, which would be IST, right? It looks like that naming convention is based on tz database - Wikipedia (from Time in India - Wikipedia). So is this a matter of expecting Asia/India to appear in the list instead?
But that’s not the field that I’m referencing. Rather, I’m talking about the “Region” dropdown that shows up when you have the Discourse Calendar plugin enabled.
Ooh I see now, my mistake — I believe India isn’t in the list because we’re taking holidays from a third party ruby gem:
and it doesn’t appear they have any Indian holidays listed yet. China is also not in the list for the same reason. Unfortunately this isn’t clear to anyone trying to change the dropdown. We are aware of the limitations of the current holiday list, and have been looking at ways to improve it.
