Help needed with light transition

I want to use my dimmer switch to:

• switch on at 12% at 12:00
• ramp up to 100% over 5 hours
• ramp down to 12% over the next 5 hours.

This is what I have at the moment, but I can’t figure out how to impliment all the automation steps I have above:

  trigger:
  - at: '12:00'
    platform: time
  condition: []
  action:
  - data:
      brightness_pct: 100
      transition: 18000

    service: light.turn_on
