Age and birthday questions
How old am I today in years, months and days?
Choose your date of birth to see your completed years and the remaining calendar months and days. The calculation uses your device's local date.
How many days until my next birthday?
Enter your birth date and the page shows a live countdown in days, hours, minutes and seconds. If your birthday has passed this year, it counts down to next year's date.
How many days have I been alive?
The result includes the calendar days from your date of birth to today, including leap days in leap years.
Why is my age not simply the current year minus my birth year?
Your age increases on your birthday, not on January 1. If your birthday has not arrived yet this year, subtract one from the difference between the years.
When is the next birthday for someone born on February 29?
In a non-leap year, use March 1 as the birthday. If the date you are calculating for comes before that year's birthday, subtract one from the difference in years, then count the full months and days since the last birthday. This calculator also uses March 1.
