ONE Direction = ONE hundred years
1D = 100Y
One Direction, an English-Irish pop boy band will celebrate 100th combine birthday 17th April 2013
Combined birthday is a special birthday for two or more people. It is easy if you know your age in days. Just add up all the ages in days and divide the number of days by the number of days in a year. It is 365.2422 - tropical year. It is not 365, becouse every 4 years we have leap year. For it we have calculator, click here.
Just add up the ages of Niall, Zayn, Liam, Harry and Louis and it will be 100 years on 17th April 2013! Total combine age in days on 17th April is 36,527. 36,527 divided 365,24 is 100! You can check it on 1D calculation result.
Of course you can click on the button "Add name" and add your birthday to calculate your own combined birthday with One Direction. You can also delete the calculation using the reset button, and then choose your other favorite celebrities by clicking on star symbol

We would like to celebrate 1Ds birthday. We asked mum if we could use face paints. It was fun. We would like do it again on 17th April, but it is Wednesday and we have to go to school. Maybe we can do painting only on our hands. Please, could you share with your friends this information about 1D celebrating 100 years. On their combined birthday, 17th April they have a concert in Birmingham. If you are going to that concert, please could you tell 1D Happy birthday for us! Thank you. We can not go to 1D concerts yet, maybe when we are older!

I hope you like our webpage and all of the fun celebrations about 1D. I am working with my friend on this calculator for more than 2 years and there is still a lot more to do. If you have some comments, feel free to email me on firstname.lastname@example.org. Find out more about me, the calculator or who is helping me. Some information is slightly old. Now I am 10 years old and my younger sister Martina is helping me. She is very good at spelling and helps with writing articles.
