Calculate age of world in Islam

I have few Question About calculating time period according to Islam

**Is there anyway to calculate how long this Universe has existed for Quran or Hadith?** **How long did Hazrat Adam(a.s) lived?** **For how long human has been living in this world?** I have been confused about the calculation of time these question have been in my mind for long time now. I want to if there is a answer in Islam about this. I know will be hard to tell but is there a time explanation in Islam. I know there were no units of second and hour so how Allah calculate time?
