Calculate your exact age in years, months, weeks, days, hours, and seconds. Includes Next Birthday Countdown, Western Zodiac, and Chinese Zodiac.
Healthy Tips & Guidelines
- Use this tool to calculate your exact age in weeks if you are tracking a pregnancy or your baby's developmental milestones.
- Enter the purchase date of your electronics or appliances to easily check if they are still within their 1-year or 2-year warranty period.
- If you are applying for a visa or government document that requires your age 'as of January 1st', simply change the target date to Jan 1st of the current year.
- Have fun with it! Calculate your 'half-birthday' by finding the exact day you hit X years and 6 months old.
Common Mistakes to Avoid
- Manually calculating age by simply subtracting the birth year from the current year, which is inaccurate if your birthday hasn't happened yet this year.
- Forgetting to adjust the time zone if you were born on the other side of the world, which can technically shift your exact birth date by one day.
- Trying to divide your total age in days by 365 to get your age in years, which will be slightly wrong because it ignores leap years (divide by 365.25 instead).
- Using a basic calculator to track a newborn's age in months instead of weeks, which is the standard medical metric for infants.
