determine if date in one table is between two dates in another ms access table

I have 2 Access tables - an address table and an event table.

The address table has a client id, address effective date, zip code and county.

The event table has the client id and an event date.

Both tables can have multiple entries for each client id.

I need to create a report that shows what zip code/county was associated with a client ID at the time an event occurred.

So I need to determine if an event date occurred between 2 consecutive address effective dates and then return the zip code and county for the earlier address effective date for each client id.

But I also need to determine if an event date occurred after the latest address effective date and return the zip code and county for that latest address effective date.

The data would look something like this:

I have no idea where to start or if this is even possible within Access.   Any help offered would be much appreciated.
