How long will it take for the moon to drift far enough away from earth that the lunar month extends by a day? Or two days?
Working on a worldbuilding project for a dnd campaign, and want to subtly hint that its super far into the future with the lunar calendar. If you also know of any websites that can generate star charts of what the night sky will look like in millions of years, that would also be great.
In our reality with our orbits, your thinking centuries minimum and millennia easily. It looks like 3.8 centimeters a year, if this website is close to accurate.
