Frequently Asked Questions.
Age is calculated by finding the difference between your date of birth and today's date (or any chosen date). The calculator accounts for varying month lengths and leap years to give an exact result in years, months, and days.
Your age in days is the total number of days from your date of birth to today. Our calculator displays this along with weeks, hours, and minutes lived.
Your next birthday is the upcoming anniversary of your date of birth. The calculator finds the next occurrence of your birth month and day and shows the number of days remaining.
