Common Mistakes to Avoid
Counting the birth year as a full year
Fix: If your birthday has not occurred yet this year, subtract one from the year difference. The calculator handles this adjustment automatically.
Using the wrong date format
Fix: Always use YYYY-MM-DD (ISO 8601). Entering 05/15/1990 may be interpreted differently depending on locale settings.
Forgetting leap years in total days
Fix: The total days count uses actual calendar time, which naturally accounts for leap years. You do not need to adjust manually.
