From your profile, it appears that you are from Himachal Pradesh and that you are interested in engineering. You haven't specified which diploma course you are interested in, so I'm assuming it's diploma in engineering only. If your query is specific to your state, admission to diploma in engineering courses is done through HP PAT, and the tentative date for the release of application forms is September this year.
