About the Redesign

If you visited this site prior to September 15th, 2018, you've no doubt noticed that I've since launched a complete redesign of the website.

If you're not happy with the new design, I sincerely apologize. I would have preferred to keep the old desktop design, but considering the majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices, and considering Google is now penalizing websites for not being mobile/thumb friendly, I was left with no choice but to switch to a responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site (mobile, desktop, and ad-free member) into a single design, this will free up a ton of my time for working to make the mobile-optimized calculators more desktop/laptop friendly. In fact, some of the redesigned calculators already offer a desktop-optimized form that becomes visible when you increase the width setting of the calculator (within the "Calculator Preferences" expandable panel).

Thank you in advance for your help and patience as I work to improve the redesign.

Age Calculator

This calculator will calculate your age in years, months, and days -- as of any date of your choosing. The calculator will also translate that age into how old you are in terms of months, weeks, days, hours, minutes, and seconds. Plus, the calculator will tell you how many days until your next birthday, and on what day of the week it will fall on. And finally, the calculator can even tell you on what date you will turn a certain age.
