Why did you delete your earlier question? I was busy posting an answer to it and it disappeared out from under me :(

Good thing I saved the answer:

   matchresult = regexp(YourCell, '^[a-zA-Z]{3},\s[a-zA-Z]{3}-\d{2}-\d{2}$');
   nomatch = cellfun(@isempty, matchresult);
   dateless = YourCell(nomatch);
   datelike = YourCell{~nomatch};

Caution: this will not accept single digit day of the month as being a date. But it will accept any three letters as potential weekday name or month name. It will also not accept spaces before or after the date. (Some of these are easy to change but I am sticking with the format that you presented.)

thanks but it didnt work. When I click on datelike I only get one result which is 'Thu, Oct-08-15'. The rest is being ignored. Why is that?

'Thu, Oct-08-15'
'Thu, Oct-01-15'
'Thu, Sep-24-15'
'Thu, Sep-17-15'
'Thu, Sep-10-15'
'Thu, Sep-03-15'
'Thu, Aug-27-15'
'Thu, Aug-20-15'
'Thu, Aug-13-15'
'Thu, Aug-06-15'
'Thu, Jul-30-15'
'Thu, Jul-23-15'
'Thu, Jul-16-15'
'Thu, Jul-09-15'
'Thu, Jul-02-15'
'Thu, Jun-25-15'
'Thu, Jun-18-15'

brackets were wrong. now it worked. thanks

     matchresult = regexp(YourCell, '^[a-zA-Z]{3},\s[a-zA-Z]{3}-\d{2}-\d{2}$');
     nomatch = cellfun(@isempty, matchresult);
     dateless = YourCell(nomatch);
     datelike = YourCell(~nomatch);
