Frequently Asked Questions
- How is age calculated?
- We take the full number of years between your birth date and the "as of" date, then break down the remainder into full months and days.
- What if I leave the "as of" date blank?
- The field defaults to today's date, so you get your current age unless you change it to calculate age as of a different date.
