Hello,

To be eligible for NDA the candidate should be between the age limit of 16.5 years to 19.5 years and must have passed class 12th from a recognised board. So to be eligible for NDA 1 2022 the candidate must be born between July 2, 2004, to July 1, 2007. As you are born on 28th July 2007 you will not be eligible for NDA 1 2022 but to be eligible for NDA 2 2022 the candidate should be born between January 2, 2005, to January 1, 2008 so you will be eligible for NDA 2 2022 as long as you have passed your 10+2 level.
