I'm a little stuck... Click here to teach me more about this clue!

'holiday with potential mates' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'renders obsolete on' is the wordplay.
'renders' becomes 'dates' (dating is a kind of rendering).
'obsolete' becomes 'out' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' is a charade indicator (letters next to each other).
'dates' after 'out' is 'OUTDATES'.

Can you help me to learn more?
