Calender entries more than 3 months old disappearing

[True Believer]

I've just noticed that none of my calendar entries prior to January are still there - and even some of those have gone. Does anyone know why this would be?
I've looked in Settings/Mail, Contacts, Calanders but can't see anything that would enable all my calander entries to be kept.
Hoping you can help.
Thanks

is this an iTunes problem?

Connect your iPhone to your computer, within iTunes highlight your device in left hand column, click "info" next to summary, scroll down to "sync iCal calendars", you will see a checkbox labeled "do not sync events older than ____days...

Check or uncheck or choose the amount of days..

Of course these are directions for Mac/iCal users..
