Is saturday evening the right moment for a monthly AT ?

I was just wondering what people think about this. I feel like saturday evening is often an evening that you plan events with family/friends that you don't want to skip for an AT. On a regular mid weekly working day one generally has less things to do in the evening maybe? Just a thought. I've seen some in-game complaints about this because people already know they're gonna miss the next monthly AT. I don't have a personal preference, but it might interesting to see what the community thinks.
