    You should always store your dates in Y-m-d format because that’s the only way you can sort them properly. You’re running into advanced problems here because you’re issuing a SQL query but your custom fields are in fact TEXT fields (that’s how the postsmeta table is defined). So you would have to cast your values as date values, which is a pain. Usually it’s easier to let MySQL sort the dates as strings (thus my recommendation to store dates in Y-m-d format).

    Once you have dates being SORTED correctly, then it’s a matter of FORMATTING them using php’s date function. The CCTM does have a datef output filter https://code.google.com/p/wordpress-custom-content-type-manager/wiki/datef_OutputFilter as a convenience, but often using PHP’s date function is easier.

    There are 2 questions here, neither of them are particular to the CCTM, but I hope the above helps.
