Here are the list of servers time on the highest amount of players and the lowest amount of players base on my experience. If you notice more of the other server, feel free to add it in the comment and I will edit this post.
The time I use is GMT +0, so you have to add base on your own global position. Also, this schedule may incorrect at WEEKEND.
Us beginner server
Always crowded = more than 30 players everyday
US-1 server
At 7 AM to 10 AM = 6 to 13 players (lowest)
At 10 AM to 4 PM= 12 to 20 players (average)
At 4 AM to 7 AM = 20 to 30 players (highest)

I didn’t play in UE server because it’s too lag for me. But I noticed that this server is always have the lowest player in my server list.

There’s might be some time error because I use my local time (GMT+8) and convert it to GMT+0. I’m not good at math. lol
