Know Your Age but Forgot Your Birthdate? Smart Multi Calculator Solves It in One Click

During form fillups, applications, or official documentation, it often happens that you know your age (example: 24 years 3 months 10 days) but you don’t remember the exact date you were born. Maybe the documents are missing or you don’t recall it correctly. To solve this instantly and accurately, we created the Smart Multi Calculator — which not only calculates age but also provides Percentage, GST, and EMI calculations in one place.

Quick Summary:
• How to calculate Age → Years, Months, Days.
• How to find DOB (Date of Birth) from Age.
