Delete log files by age

On one server we have, there are 7 log file directories which contain both logs and configuration files. Each day the programs create a new log file. I haven’t found a way to input the file mask (For example: C:\Gips\Log\boss.*, o:\application\alarmserver\current\log\alrmserv\socket\*.log) and delete files older than a specific date. Windows 2000 command line commands don’t seem to have that ability, and neither does any program I’ve seen. I would like to run one program or script that would take the file masks I give it, and delete those that are older than a month. Any ideas would be helpfull.
