Gregorian to Maya LC conversion

[VitalyChe]

Thanks for the lib!
Is there any way to convert Gregorian to Maya LC?

[drewsonne]

Good question. I don't actually think there is at the moment. I'm working on the library today, so I'll have a crack at it.

Would be nice to have it, as it's kind of a blocker to start looking into Mayan dates

[drewsonne]

I don't have a good way to handle the conversion between julian and gregorian, so I'm probably not going to get a chance at this until I finish the calculator driving this project.
If you're up for it, you can take the test cases and the method I was looking at here https://github.com/drewsonne/maya-dates/compare/feature/western-to-lc?expand=1 and try and implement it.

If you're looking for getting started with understanding maya dates, I'd try running something like

import {origin} from "@drewsonne/maya-dates/cr/calendar-round";

console.log(`${origin}`)
let cr = origin.next()
console.log(`${cr}`)
while (!origin.equal(cr)) {
    console.log(`${cr}`)
    cr = cr.next()
}

should give you an idea of how the calendar round works.

Thanks, I'll have a look
