Calculate exact age in years, months, and days. See total days old, next birthday countdown, and age on any target date.
This age calculator measures the time between a birth date and a target date. It breaks the result into full years, remaining months, and remaining days, then also shows total days and weeks for a simpler view.
The tool starts with the target date and subtracts the birth date. It borrows days from the previous month when needed so the final answer stays in normal calendar terms instead of only raw day counts.
Use a birth date and a target date. The result is the number of full years completed plus the extra months and days since the last birthday.
Yes. This is useful for checking school age, retirement milestones, or how old someone will be on an upcoming birthday.
The tool also shows the full number of days between the two dates, which is often the easiest way to answer that question.
The next birthday is the next time the same month and day appear after the target date. The countdown is the number of days until that date.
