Age Calculator

“How old am I really?” Seems simple—until you need to calculate days since your 18th birthday or figure out if you’ll pay off your mortgage before retirement. Manual math becomes a puzzle: leap years, varying month lengths, time zones… What if you need to compare two people’s ages or count down to your child’s first day of preschool?

That’s why we built this Age Calculator—your shortcut to clarity.

Why You’ll Love This Tool:

Precision down to the second – Even if you were born at 11:59:59 PM!
Compare any two dates – Birthdays, deadlines, anniversaries, or future events.
Zero formulas, zero stress – Get accurate results in 2 clicks.

How it works (it’s effortless):

1. Enter a start date – Your birthday, project kickoff, pregnancy date, etc.
2. Add an end date – Defaults to “now,” but choose any future/past event.
3. Click “Calculate” – Done!
