Trabajé medio día.
When describing the duration of 'half a day', use the two separate words. 'Un mediodía' would mean 'one noon', which doesn't make sense in this context.

Frequently Asked Questions
Does this one-word vs. two-word rule apply to 'medianoche' (midnight) too?
Yes, it's exactly the same concept! 'Medianoche' (one word) is the specific time 12:00 AM. 'Media noche' (two words) is a duration, meaning 'half the night'. For example, 'La fiesta duró media noche' (The party lasted half the night).
Why is it 'medio día' and not 'media día' if 'día' ends in 'a'?
Great question! This is a classic Spanish exception. Even though 'día' ends in 'a', it's a masculine noun. That's why we say 'el día' and 'buenos días'. So, the adjective 'medio' stays in its masculine form to match.
