I am having a wierd problem while filling up the online admission form of Kulachi Hansraj school, ashok vihar. It say that the child's age should be 3+ for nursery admission. My son will 3 years and 9 months old on 31st march 2014. So, the age should be perfect. But when I click on submit button, it says "Invalid age" of child. What could be the problem? I have checked and tried many times and I am double sure that I am filling up the correct age. Can somebody help?
