Why Calculate Your Age with Time Included?

Your age isn’t just the number of birthdays you’ve celebrated—it’s the continuous count of every year, month, day, hour, and minute since the moment you were born.

People calculate their exact age for many reasons:

• Birth certificate or legal applications

• Astrological or numerology charts

• Personal milestones

• Fun trivia to share with friends

If you were born late in the evening, for example, your real age may be hours younger than you think on your birthday.
