Learn how to use our advanced Age Calculator below.

  1. Enter the Date: Find the text box labeled “Enter date”. Here, input the date for which you want to calculate the age. The site accepts various formats, including MM/DD/YYYY (e.g. 03/15/2010), DD/MM/YYYY (e.g. 15/03/2010), or full month names (e.g. March 15, 2010).
  2. Initiate the Calculation: Click on the “Calculate” button positioned below the input box. The website will then compute the age based on the provided date.
  3. Review the Results: Once calculated, the site will display the age in several formats: years, months, days, weeks, hours, minutes, and seconds, offering a detailed view of the age since the entered date.
  4. Handling Invalid or Future Dates: If an entered date is in the future or otherwise invalid, the site will prompt you to enter a past date that is valid. It may also suggest alternative dates based on your input.
  5. Using Date Suggestions: If the site cannot recognize the date format, it might provide suggestions as clickable links. Selecting one of these will automatically fill the input field with that date.
  6. Clear and Reset: To perform a new calculation or correct an error, use the “Clear” link located below the calculate button. This will empty the input field and clear the displayed results.
  7. Share Your Calculation: After the age is calculated, a “Copy Link” option becomes available, allowing you to create and share a link with the specific date calculation.
  8. Flexible Date Format Support: The calculator is capable of interpreting a range of date formats, including dates without separators, dates with two-digit years, and dates with ordinal suffixes (like ‘2nd April 2005’). It adapts automatically to the format used.

Supported Inputs supports a variety of input formats for dates.

  1. Standard Date Format (MM/DD/YYYY): This is the most common format, where you enter the month, day, and year in numeric form, separated by slashes. Example: 12/31/2000 for December 31, 2000.
  2. European Date Format (DD/MM/YYYY): Some users might enter dates in the day-month-year format. The calculator can interpret this format as well. Example: 31/12/2000 for December 31, 2000.
  3. Year-Month-Day Format (YYYY/MM/DD): Although less common, this format is also supported. Example: 2000/12/31 for December 31, 2000.
  4. Month Name Formats: The calculator can interpret full month names or their abbreviations, followed by a day and a year. Examples: December 31, 2000, Dec 31, 2000, 31 December 2000.
  5. Numerical Inputs Without Separators: The calculator can process dates entered as a continuous string of numbers. For 8-digit inputs (MMDDYYYY or DDMMYYYY), the code distinguishes between the month and day based on plausibility (e.g., if the first two digits are greater than 12, it assumes a day-month-year format). Examples: 12312000 could be interpreted as December 31, 2000.
  6. Two-Digit Year Inputs: If a two-digit year is entered, the calculator makes an assumption based on the current year to determine the century. Example: 12/31/00 might be interpreted as December 31, 2000.
  7. Variations with Dots, Commas, and Spaces: The calculator can process dates where the components are separated by dots, commas, or spaces instead of slashes. Examples: 31.12.2000, 31, 12, 2000, 31 Dec 2000.
  8. Ordinal Date Formats: Dates with ordinal suffixes (st, nd, rd, th) are also recognized and processed correctly. Example: 1st January 2000.
