as above

is it better to switch on yr lights in the morning or night time?

and does it matters?

Does not matter as long as you follow a routine light cycle... there should be a regular 'day' period and a regular 'night' period.

It makes no sense for you to switch on your tank in the morning and come home to a dark tank at night if you follow the actual timing outside.

My lights come on at 4pm and go off at 1am daily. Weekends... I manually switch them a little earlier... they get extra long 'daylight' during the weekends!

same leh i normaly let them have longer hours on weekends but i realise that in the morning if u switch on the lights the corals open bigger seems they like it

Depends on which corals.

Hard corals will probably be expanded with feeding polyps all out... to catch zooplankton at night. So in the 'morning', if you switch on the lights, they seemed 'bigger'.
