I would like to move a few dozen events from one calendar to another.
Is there a way to do this, without having to delete each event and re-create them on the new calendar?
Clarification
By non-manual method, I mean not having to delete each event, then having to recreate each event with descriptions, times, invitations, etc. Perhaps this wording was poor, but the accepted answer does utilize Google's system for moving an event rather than me having to simulate the effect via delete/create.
