In a spreadsheet in Google Spreadsheets, I’m trying to solve this:
17/02/2012 banana
17/02/2012 banana
17/02/2012 banana
17/02/2012 apple
18/02/2012 apple
18/02/2012 apple
I need a formula that returns how many times an unique value appears in a given date.
Example:
- 17/02/2012 – two unique values
- 18/02/2012 – one unique value
Can anyone help?

I don't know how to create a formula, but you can insert a PivotTable to get the same results.
On the spreadsheet enter your data and include a heading for each column (so on your reference above you would add column headings: "date" and "value".
Then choose "Data ... PivotTable report" from the Menu. You are now working on a new tab which is the PivotTable and it references the data on your spreadsheet tab.
In the Report Editor on the right side of the screen make the following selections: "Rows - Add field" and choose "Date"; then choose "Values - Add field" and "Value" ... then "Display: Value, Summarized By "COUNTUNIQUE"
The PivotTable now shows you the unique entries for each date.
