How this calculator works
Age is calculated as a true calendar difference between two dates, not just a division of days by 365 — it counts whole years, then whole months within the partial year, then whole days within the partial month, the same way you'd count it on a calendar by hand.
Change "Age As Of" to any date to answer questions like "how old will I be on my wedding day" or "how old was I when this photo was taken" — it doesn't have to be today.
