Date and Birthday Calculators

Today I learnt how to find out when I am 1 billion seconds old.

The website timeanddate.com has a useful Date Calculator which "enables you to add or subtract days, months and years to a date to calculate a past or future date." The site also has a (less useful but more fun) Birthday Calculator which lets you calculate, amongst other things, when you are 1 billion seconds old. The Date Duration Calculator lets you calculate the duration between two dates, so you can find out exactly how old you are right now, if you have nothing better to do...
