Moon age (days) calculation

[vdurnev]

Thank you for your work, Richard

What is the right way to calculate Moon age (Moon days) using your library?

[ELY3M]

This is kotlin

    val moonage = 29.0 * (normalized / 360.0) + 1.0
    content += "Moon Age: " + moonage.toString()

I don't code in Kotlin, but it's enough like Java that I'm reasonably confident you don't need the explicit moonage.toString(). Simplifying a bit, you can think of string concatenation terms all being wrapped in an implicit String.valueOf(x) call.

What is the precise definition of Moon age/days here? I'm not familiar with this.
