Fun life milestones you never think about
Birthdays come once a year, but your life is full of other milestones that go unnoticed. When did you turn 10,000 days old? When will you reach 1 billion seconds? This calculator finds every one of those dates — and tells you how many days until the next one.
Each milestone comes with a downloadable story ticket you can share on Instagram, Twitter, or anywhere you celebrate life's weird math.
