After Hours and Weekends Responder

After Hours and Weekends Responder

I recently had to set regular work hours of 8:30am-5pm Mon-Fri and off weekends due to mental health / suicide issues. 

While I have communicated my work hours to my clients and released the ones who weren't on board with them - I could still use an after hours / weekend responder. The out-of-office responder won't work for what I want to do and the rules seem to tie to support tickets. Thoughts? 

"Dear Client: 

Thank you for emailing. If you are reading this, it's outside my normal business hours of 8:30am-5:00pm Mon-Fri.  My company is closed evenings and weekends. I will respond within 1-2 business days. Thank you for reaching out. 

Best, 

Ron Hall
Owner, Lemur Technology LLC."

Any idea how to set this to fire from 5:00pm in early evening to 8:30am the next morning Mon-Thurs and 5:00pm Friday - 8:30am Monday to cover the weekends? Sort of like setting Google business hours in a business listing where you can set each day different.
