Hi friends..
Do you know I am so smart and intelligent haha. This is not my feeling my relatives told to me and to my parents do you know why it is..? recently we had a function at my home they asked my age usually everybody says their age in years roughly but I said my age in Years with Months and Days perfectly with in a seconds, so they felt that, but the truth is I used one App to get that exactly
So you also want to be Cleaver, Smart and Intelligent in front of your relatives & friends just follow the app shown in this video and try it.
From now onwards if any one asks your age just told them your age with months and days along with years and surprise them in a short span of time.
This is mainly used to calculate age from date of birth.
