…Start with a lunar month roughly 28 days, divided by 24 (earth hours), leaving approximately 1.167 Earth hour to 1 lunar hour? Would have to use a terrestrial Earth point of reference to determine a 'lunar day'.
…Anon is highly speculating, of course. Visualizing a waxing/waning of the Earth. Overthinking this damn puzzle.
…Would be funny if lunar time was +28hrs from GMT. Damn it, anon is going to be pondering this all fucking day.
