To be able to “solve” the MO:ULa pod ages in a convenient manner it helps having a pod age calendar (or clock). Try e.g the Pod Clock application, available for most platforms. There is also information about the Pod Age Calendar available on the web, but its actual calculations does not seem to work in any modern web browser. Your best bet would be something like Opera 12.
Update: I can also confirm that the Pod Age Calendar page works in IE7 and IE8.
Update 2: A very quick reaction from the maintainers of that site! We already have a fix!
