Precision

Well, I'm getting nowhere with the damn calendar. - I can partly understand the calculations, but then I come across calculations that I cannot understand. I don't know how one came up with this or that value in the descriptions.

There are some formulas for calculation, but that's no use to me if I don't know how the values were arrived at. Difficult! - The people who came up with this calendar must have had a lot of time.
