Add Vietnamese calendar

[trmdi]

Bonjour!

I want to add Vietnamese secondary calendar (Lunar Calendar).
It's only visible when the language is Vietnamese.
When there are multiple clocks, it's only visible on clocks with Asia/Ho_Chi_Minh timezone.

Look forward to your thoughts!

Thanks @trmdi !

I wanted to do something similar when I came across the Iranian calendar while translating to Farsi, but it was a lot of work 😅

Your implementation seems pretty clean so thank you for that! I'll look into adding more calendars, and adding a toggle option. Can't tell when though.

Do you think this calendar should be enabled by default for Vietnamese users ?

Do you think this calendar should be enabled by default for Vietnamese users ?

Yes, I think so. Since printed calendars have it, and Samsung phones also enable it by default.

Interesting, enabled by default it is 👍

So this could be merged for the next release or you have other requirements? (besides adding more calendars, which should be done later, one by one)
I really like this extension and want to introduce it to my friends. I hope it will be available in the next release.

It will be in the next small update: 20.3.0 !
