Hi Product Hunt! My name is Kornel, I’m the maker of age-calculator.org, a collection of different type of age, birthday and date calculators. The main function of this free web app is to calculate the exact age at any date or the time difference between two dates. Age-calculator.org also can calculate special age related topics like Heart rate by age, or the moon phase on your birthday. You can also easily find answers to the following questions: How old will I be in the future?, How old is my cat/dog in human years? What is my zodiac sign? How many days until my next birthday? Hope you guys find this fast and lightweight tool really useful. Also if you have any idea or recommendation on what kind of “Age Calculator” should I make in the future, let me know. Many thanks, Kornel
