First Moon Landing: 19 years x 2

According to the official story, man first landed on the moon 38 years ago today. What makes this special is that 38 years is divisible by 19. And 19 is the period of the Metonic cycle, the approximate common multiple of the tropical year and synodic month.

6939.6075 days =  19 tropical years
6939.6887 days = 235 synodic months  

What this really means to us is that the phase of the moon today is very close (within about 6 hours) to what people saw 38 years ago on July 20, 1969. Very cool.

So, enjoy the view of the moon today and remember back to when we as a global humanity first bought the story that man had finally made it to the moon. 😉
