Transfer one calendar into another ical5?

[Dal123]

I want to transfer all the events from one calendar into another calendar. I do not wish to add it under the existing calendar as I already have too many calendars.
How can I transfer all events under this calendar into the new one?
Using mac osx lion ical5.

Select the calendar you want to export and File/Export and save the file. Then import that file into the second calendar.
