Will Angkor be much less crowded on weekdays than weekends?

I’m heading to Siem Reap on Friday and have 4.5 days. Was originally going to do Angkor the first two days but realized that’ll be the weekend (didn’t plan thinking of that since this is part of a larger trip.) I imagine there’s always large crowds, but would it make a huge difference if I did Angkor on mon/tues instead of sat/sun? Any other tips appreciated as well :)
