What is the frequency of network difficulty change

[Nheer]

In my study to know more about bitcoin I discovered that difficulty is a measure of the complexity of finding a hash below a given target or the difficulty of mining a Bitcoin block. But I still have problem understanding and I need further clarification about
How blocks of difficulty are stored? And What is the frequency of network difficulty changes?

In short: difficulty is stored (in compressed form) in header field "bits" and difficulty adjusts every 2016 blocks.

More precisely, the target is stored in the nBits field in the header. The difficulty is a value that is computed from the target.

Bitcoin network difficulty will be re-targeted each 2016 blocks.

Bitcoin Difficulty Estimator gives you estimation for a next difficulty change. It's estimation with wide range of lower and upper change estimations. Estimations for next change is from 4% to 13%.
