anyone heard of tradition of starting voyages on new moon

[raaaid]

well ponder this

phileas fog lives in this planet with a counterotating sun and moon

after his travel around the wolrd he counts 79 suns and 81 moons

dont you agree then he could use a combination of sun-moon dial he could easily obtain longitude which is interesting for navigation?

how?

from greenwhich time difference will be always zero, both sun and moon take same time to make a revolution in the sky

but for phileas fog who travelled around the world he will count a 2 days difference between sun time and moon time

so the rest is easy

360º 2 days
90º 12 hour
30º 4 hour
15º 2 hour

so whats wrong with this?

why this isnt in books?

answer right any of this and youll have your poll

but i bet for sure like when the time i had no money and i bet one euro i could drink a beer of one swallow
