Is it correct to say:
I am available any day after Tuesday between 12 Noon and 6 PM.
I would move the "time" portion of your message and change how you specify the day.
I am available between 12 noon and 6pm every day from Wednesday onwards.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
If you think you may get an appointment at the weekend, add '...including Saturday and Sunday'.

Note that a better title would have been 'I am available any day after Tuesday....'
Extract from the Posting Guidelines:
'Thread titles should include all or part of the word/phrase being discussed.'
I think it's fine.
