Utilized with eclipses, the Metonic Cycle can also be employed to determine astronomy constants.
Of course longer periods (it is not a true cycle) offer greater precision.
"... accurate integer equation of lunar synodic with the apogee-perigee period ensures greater interval constancy of eclipse observations."

Full moon, says #Meton. And Meton should know.

#Meton says today is a full moon and a total lunar eclipse. And Meton should know.

«The Moon Machine» hiess das Referat, das ich am 15th International Illustration Research Symposium an der Koç-Universität in #Istanbul gehalten habe. In der Hauptrolle: mein 3D-druckbarer #OpenData-Mondrechner #Meton und seine historischen, archäologischen und astronomischen Hintergründe.

Und wer selbst einen Mondrechner braucht: Nur zu! https://www.thomasweibel.ch/?post=rechner-aus-dem-drucker
