This is, of course, completely ignoring the fact that in [[Real Life|the real world]], the calendar and timekeeping methods we use here on Earth would, almost without a doubt, totally not work at all for 99.99999% of all the other planets in the universe. Because, surprise, surprise, planets orbit their stars at their own unique speeds, and they rotate on their axes at different rates, too, both of which are influenced by a large number of factors and can range from nearly static to extremely fast.
 
Just to put it in perspective for you: One "day" on Venus, our closest neighbor planet, is equivalent to approximately 117 Earth days because its rotation is so much slower than ours. On the other hand, one "year" on Venus is equivalent to 225 Earth days because Venus moves a bit faster, and its orbital path is shorter than Earth's. (<ref>The 243 Earth days figure you may see bandied about as the length of a Venusian day is its sidereal day. The mean solar day is shorter due to Venus's retrograde rotation, whereas planets that rotate prograde have a solar day that is longer than the sidereal day.)</ref> [[It Got Worse|It gets weirder]] – one Mercurian day is about 176 Earth days, or precisely ''two'' Mercurian ''years''. (The precise 1:2 ratio is due to a 3:2 spin-orbit resonance.) Yes, that's right – on Mercury, a day is two years. (Feel free to speculate about whether dates like April p.m. have any meaning.)
 
When this occurs (even more bizarrely) in a [[Time Travel]] story, it's [[San Dimas Time]] and/or [[Meanwhile in the Future]].
