1 or 2 day Community Days?

I'm sure the amount of money they rake in across both days will decide if they continue this trend. I've never had issues missing a community day but I would like it immensely if they continued spreading it over two days. I've seen a lot of people complain about them flip-flopping the days (Saturday working better than Sunday for some and vice versa), having it on both days would mitigate this.

I also hope giving until the following Monday to evolve for the special CD move stays as well. It's frustrating trying to decide what's worth evolving and what isn't within the last 15 minutes or so.

2 days, but cancel the effects of CD if the account was used during the first day. That way everyone has two time slots to choose from.

If they do go back to 1 day they should at least let the evolution for the special move last until midnight that night, that way even if someone was working and didn't get to go catching, they could still have time to evolve some mons they already had for the exclusive move

I realize this is not helpful, but I hate the community day and feel it is totally unfair to a lot of players. I haven't gotten any of the special moves that can be only gotten during these events because I am not available at that time on the weekends.

I would prefer if they made it a 24-hour event on one day so at least nearly everybody could participate at some point. I get that the focus is on kids and not adults who may have to work, but it still seems totally unfair to me.

I'll tell you Monday.

Right now? I love the idea. Larvitar day, for instance, was almost a complete bust for me because my wife and I made the mistake of deciding to go somewhere new, going at the last minute, and not being properly prepared for the location and situation, so we lost a full hour of playing because we had to find parking (it was a public park with limited parking), we had to find the Pokestops (about 1/3 of what we were used to playing with on Community Day) and no washrooms nearby (and when you've got a 7yr old daughter in tow, you need to know where the washrooms are).

So I've got a personal reason to like it, but until I've gone through it over the two days, I won't know what I really think of it. As you can see, my like for this is based on being able to make up for my own mistakes, so...

There is no downside to having a 2 day CD (lol?). The only "theoretical" downside would be if you cannot attend both days and you dont want other people getting twice the pokemon (If I dont get it then no one should get it).
At the time PoGO has no competitiveness so this shouldnt be a problem.

I think this model going forward would be perfect. Everyone will want to hit one or both of the event windows so I assume total player activity will be greater than with just one 3h window.
Letting us evolve after the 3h window lets us concentrate on playing, which will mean more items used->more boxes bought->more revenue. I assume until now many people have skipped using their grind items for the last 30 minutes because a lot of that will be wasted on appraising and evolving instead of catching.

I mean, I'll do both of this one for Stardust, but in general I think 1 is enough. I'd probably play both every time, but I'd enjoy one more.

What sets Community Day and similar events like Zapdos Day apart from other events is the extreme time localization. Other events last months, weeks, or days; you can do them at your leisure. But with Community Day, you have to do it now or never. Everything that extends this time makes Community Day less special.
