I was so astonished when my guildies started to talk about timewalking, while all I was seeing was the Arena icon!
Indeed, there are two events now and you should be able to see the appropriate Dungeon Finder section.
I started to think Timewalking is on a separate rotation now but sadly that's only moving one of the events out of the next week, perhaps for the sake of Tomb of Sargeras.
And what's that mysterious switch in the fourth week of the May? (US realms may have it different.)
Sorry if it's only mine calendar messed up and everyone else has already seen it.
