Has she had her day? (3)

I believe the answer is:

eve

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

I believe this clue is a triple definition!

'has she' is the first definition.
'Eve' can be an answer for 'she'. I am not sure about the 'has' bit.

'had' acts as a link.

'her' is the second definition.
(I've seen this before)

'day?' is the third definition.
(I know that eve is a type of day)

Can you help me to learn more?

(Other definitions for eve that I've seen before include "Day before Christmas" , "Day before (an event)" , "Threshold" , "Adam's wife" , "Night before an event" .)

I've seen this clue in the Evening Standard.
