FAQs
Does the age result prove that I qualify for an application?
It only calculates the entered date interval. The organisation’s cutoff, document requirements and eligibility interpretation must be checked separately.
Which inputs do I need for Exact Age Calculator (Years, Months, Days & Cutoff Date Eligibility)?
Use Date of Birth (YYYY-MM-DD); Calculate Age As Of Date (YYYY-MM-DD). The built-in examples show how those fields fit together.
What should I check before using this result?
Follows standard Gregorian calendar month lengths including leap years. Check the assumptions and output against your intended task before relying on the result.
