When is MS's exact anniversary day?

Hi. can someone one tell me when is MS's exact anniversary day and if you think there is a chance we can have another surprise 2exp event that day as it has happened in previous years?-

ty.

The 11th, and I wouldn't count on it. Plus, those are always terrible days full of lag.

2x exp events always turn out to be huge headaches... I much prefered the Hunter's Luck event that we could do our own 2x event without having crowded maps or fixed times.

Which is pretty much why I almost never train during 2x events and rather use my family rep and train 45min-1h everyday.

I agree on the hunter's luck event being way better (although it sucked if you dc'ed) but I doubt they will use that event until next year's spring (if ever again).

I'd be satisfied if they gifted 4 hours 2exp cards.

I think it was the year 2008 when we had an anniversary and no exp events were announced. Then on the 11th, they had a surprise 8am~8pm x2 event, and then released the info for it and the rest of the following weeks.

We also haven't heard cash shop sales or other things like that. May is their biggest event period, so i'm pretty sure we have other stuff to hear from them. Otherwise it's going to be a huge letdown

Edit: Yep I was right

cinco de mayo

 Spoiler

But now that I think it is probably on the 11th like Dusk said. Maybe the patch had nothing to do with Maple's anniversary date.
