Age.ninja is a project of four family members. Because we do it in our free time and we have different professions and school we prefer not to share our full names or photos. We hope that it is still trusworthy. You can contact us here.
- dad - With a programmer friend I am in charge of making sure everyting works and is correct as well as on-page optimization. I studied in a technical university so I don't have a problem with the calculations. In reality, I try to learn how to make the web more seen in searches.
- mum - I work as a science techniacian but programming and web pages are foreign to me. However I found a passion in adding new celebrities and if there is time to write about them. At the moment there are more than 20,000. Recently I have been also adding to 'others' such as builldings, events, animals, famous inventions and more. Its really interesting to know about and find out more about some of the celebrations.
- Dominik - In the beginning I helped with programming. I have started studying renewable resources at University so I have less time. I still add to the web what is celebrated every day. I am currently working on the song Billboard, so that every day has a song and a link to YouTube. Its cool to play the songs which were played when I was born or to know what was popular in different years.
- Martina - At the moment I am studying at College and in two years will go to University. I don't understand how to make a website, but age.ninja is quite fun. I write or check every article. As I live in England I use the English version which I know, even though the web has majority of its visitors from the US. Along the way I am also learning about SEO and online marketing.
The idea for calculations came about when our family had a laugh about how old we were collectively. We found out that it is not such an easy calculation. It was quite fun and we said to ourself that it may be interesting for others as well. And when there is a calculator for combine birthday, why not be there one for other interesting things for famous celebrities. The project was created slowly as we were making it alongside jobs and school. For a long time we thought of what to calculate. It wasn't easy to make a web without much knowledge and we learnt a lot from our mistakes.
This kind of web is very complicated and it was a lot harder to make than originally thought. In the end we decide to run the web even though not every thing was ready. The important thing is that every calculation that is available, is correct and working. The web domain age.ninja was released April 4 2017, and we take this date to be the begining of age.ninja
For all of April 2017 we had 20 visitors (not including ourselves). We did not use active, paid adverts and the viewings increased only gradually. In the begining there was around 100-200 visitors monthly. From the end of March 2020 the whole family had to stay at home due to Covid so we had more time to work on the web. We improved and added a lot of calculations, celebrities and others. We added articles and learnt a lot about how to have a good web page. Slowly the number of users increased and now we have about 30,000 visitors monthly. We are very grateful for this. At the same time we added adverts and all income is for further improvement of the web.
The main goal is for users to like and be interested in the page, so they return and share the page between their friends. We will be thankful for any positive sharing.
- Half birthday
- Combine birthday for two or more people - a very unique calculation
- Animal age - dog, cat, turtle, horse and more
- Planet age - Mercury, Venus, Mars and more
- Age in time units - your age in seconds, minutes, hours, days, weeks, months
- Celebrities celebrating a birthday with you
- Interesting calculation, e.g. number of heartbeats, breaths or length of hair, nails if you would never cut them
For all calculations, you can find what day will be some round celebration. E.g. you can find exactly what day your age will be equivalent
to 10 dog years or what day you will have 100 years on planet Mercury or what day you will celebrate 1 million minutes.
We try to point out some of human's life milestones as an animal (for example get a FB as a dog or have a driving license as a tortoise ).
So don't hesitate and have a look! Maybe you will find something nice and funny. If you are looking for something you didn't find, give us a shout and send us a message and we will try to improve it.
We fight to be the best!!!
