🎭Entertainment Tools

Entertainment tools for the calculations that are fun to run rather than strictly necessary: the kind of question you ask out of curiosity, then send to a friend. The category opens with the Age on Other Planets Calculator, which converts your Earth age or date of birth into the equivalent age you would be on every planet, dwarf planet, and major moon in the solar system, based on each body's orbital period. It is a quick way to feel how differently time passes across the solar system: a year on Mercury is 88 Earth days, so birthdays pile up fast, while a single Neptune year runs about 165 Earth years, meaning almost nobody has ever had one. The thing most people forget is that an age is not a fixed number but a count of orbits around one particular star, so on another planet you have completed a very different number of laps. If you are new to the category, there is one tool here for now, the Age on Other Planets Calculator, and it needs nothing but your birth date. The category is deliberately small and is expected to grow with more novelty and educational calculators; nothing here is meant to be taken as a serious measurement of anything.
