Best time of the day to join games that u think

what time of day is best for joining matches. I need a time where I can pick the nation I want with relative ease and I don't have to wait over a long period of time to pick said nation. in my experience when you want to choose a popular nation the best time to join a match is when lots of players are joining matches(high traffic hours) . this is because lots of new games are being created meaning that you can just wait for a new server to open and join that one and pick your nation.
