FYI i've just successfully upgraded server hardware, actually doubled the RAM memory and SDD (storage) size.
Is the 19 year Metonic Cycle found in the works of ED Leedskalnin?
I was looking again at the Metonic Cycle definition of 6939.x days...and the number looked very familiar to me. I had recently seen that number or one similar to it in the works of EDL. So, I started with the number of words in his 5 works:note: By my count - don't let me stop you from doing your ownABIEH = 4781
MBSB = 1537
MC = 9225
MVA = 1547
NA = 3294
I added the 3 smallest numbers and get:1537 + 1547 + 3294 = 6378
This is not 6939.. but the difference is 6939 - 6378 = 561 days
I wondered what happened if you divide the 561 by 19 years in the Metonic Cycle and I got 29.526. This is extremely close to the official period of 29.53 days per 235 synodic months in the Metonic Cycle.https://en.wikipedia.org/wiki/Metonic_cycle
19 tropical years = 6,939.602 days (12 × 354-day years + 7 × 384-day years + 3.6 days).
235 synodic months (lunar phases) = 6,939.688 days (Metonic period by definition).
254 sidereal months (lunar orbits) = 6,939.702 days (19 + 235 = 254).
255 draconic months (lunar nodes) = 6,939.1161 days.
