Perhaps the most inconsequential information ever, perhaps

This site calculates how old you would be on Mercury, Vensus, Mars, well, you get the idea.

It also tells you things like when you'll be 300,000,000 seconds old.

You also find out how many times you have blinked, how far light has traveled, how many people have been born, how long your uncut fingernails would be, and how far a human sperm could have swam since you were born!
