Age Calculator — Find Your Exact Age in Years, Months & Days
The Age Calculator can specify the age or interval between two dates. The calculated age will be displayed in years, months, weeks, days, hours, minutes, and seconds.
The age calculator computes the difference between your birth date and any target date you specify. It counts the exact number of complete years, months, and days, giving you a precise measure of elapsed time rather than just a rounded year count.
The calculation is accurate down to the day. If you add a birth time, the result becomes even more precise, accounting for hours and minutes. This level of detail is useful for legal documents, medical records, and anyone curious about their exact age to the minute.
Time zones can matter if you were born very close to midnight and someone is calculating your age from a different time zone. For most practical purposes, the date of birth is sufficient, but adding your birth time in the calculator can improve precision.
Yes, you can enter any start date and any end date to calculate the elapsed time between them. This makes the calculator useful not just for personal age, but for measuring the duration of projects, relationships, anniversaries, or any other time span.
Your age can appear to differ by one day near your birthday due to how different calculators handle the exact birthday date and time zones. Our calculator uses the most standard convention: you complete a year of age at the start of your birthday, ensuring the most accurate result.
