Please note Tranquility Calendar itself was proposed in 1989. This is just a web representation of it.
If you are going to make a calendar that's all about the moon, find a way to make it lunar or lunisolar!
When this was proposed in 1989 , I think the intention was to get people to use it a bit! So it helps being close to Gregorian Calendar.
Though it didn't catch on, still an interesting proposal.
Not intentional, I guess I had it always wrong.
> Glad you added the Gregorian calendar option for translating between our dominant calendar and this.
Guess I couldn't do that well a justice to the mobile layout.
