Dear jianfengZ,

I just got this thread, for you question:
User needs to select date of birth of self using date picker, can I output how old the user is as far? and if possible, can I use a filter by age range and display results after stored the post?
There isn't such a built-in feature within Toolset, I suggest you try these:
1) Create two custom fields:
a) Custom date field, for example "birthday"
b) Custom numeric field, for example "age"

2) Create a CRED form of your user to fill the "birthday" field value

3) When user submit above CRED form, use CRED action hook "cred_save_data" to trigger a custom PHP function,
https://toolset.com/documentation/programmer-reference/cred-api/#cred_save_data
in this PHP function do these:
a) Get the field value of "birthday"
https://codex.wordpress.org/Function_Reference/get_post_meta
b) Use "birthday" value to calculate the "age" value, and put it into field "age"
https://codex.wordpress.org/Function_Reference/update_post_meta
4) Then you will be able to output the custom field value of age, and order the view by the "age"
