Is it possible...

...to synchronise the calender on my iPad with the calendar on my android phone, so that I only have to enter things in one?

Yes.

You could either find yourself an exchange mailbox service, or a free CalDav service. Either should work fine.

Edit: I believe Google allows CalDav access to their calendar service, which you should be able to use.
